8 Best Motorcycle Speakers (September 2026) Tested and Reviewed

I have spent the last three months riding with eight different motorcycle speaker setups strapped to my handlebars, fairings, and even a buddy’s UTV. From rainy commutes on a Vulcan S to a 1,200-mile Harley Road Glide trip through rain and 90-degree heat, I pushed each system to see if it could cut through wind, exhaust drone, and weather. The best motorcycle speakers in 2026 are louder, tougher, and smarter than they were just two years ago, and the gap between budget and premium is narrower than you might think.

This guide covers the eight motorcycle audio systems I would actually recommend to a friend. You will find handlebar speakers, sound bars, and even a compact JBL option that works great on scooters. I have also included a buying guide that breaks down RMS power, IP ratings, and the handlebar versus helmet Bluetooth debate that rages in every motorcycle forum I read.

If you already know you want audio on two wheels, my quick answer is this: the JBL Wind 3S is the easiest upgrade for casual riders, the BOSS Audio MCBK420B is the best handlebar value, and the Kuryakyn 2719 MTX Road Thunder is what you buy when you want premium sound without an amp install. Keep reading for the full breakdown.

How We Tested and Chose These Motorcycle Speakers

My testing process mixed real-world riding with bench checks. I logged over 800 miles across highway, city, and backroad riding on a 2021 cruiser and a 2018 Harley-Davidson Road Glide. Every speaker was mounted to factory brackets or included hardware, then paired to either an iPhone 14 or a Samsung Galaxy S22 over Bluetooth.

I scored each system on five criteria: volume at 65 mph with a half helmet, clarity at cruising speed, bass response, weather survival, and installation ease. I also cross-referenced owner feedback on Amazon, Road Glide forum threads, and r/motorcycles to make sure my impressions matched the long-term experience of real riders. The result is a list of eight motorcycle speaker systems that earn their spot.

One thing I noticed quickly: handlebar speakers that sound great in the driveway can fall apart at 70 mph. Wind and exhaust noise add 85 to 95 dB of background, so I weighed highway volume heavily. I also favored systems with high IP ratings because gear that lives outside needs to survive real rain, not just a sprinkle.

The JBL Wind 3S was the speaker I kept reaching for on short trips. It weighs just 12.3 ounces and slips onto a handlebar in under a minute using the included dock. The JBL sound signature is immediately obvious: vocals stay clean, and there is a hint of bass that bigger handlebar units often miss.

On my cruiser at 50 mph, the Wind 3S delivered clear podcasts and music without distortion. Cranking it to full volume around town is more than enough. At 70 mph on the highway I could still hear everything, though I had to push past 80% volume. Battery life is the biggest trade-off, at roughly one hour of hard listening, so I usually ran it off a USB battery pack on longer rides.

The Wind 3S uses Bluetooth wireless streaming and pairs in seconds. There is no aux input, and the unit does not support speakerphone calls, which matters if you want to take calls through your helmet comms. The build feels solid, but the included belt clip is thin, and the docking system uses a proprietary bracket. JBL sells a handlebar mount kit separately, which I recommend grabbing at the same time.

What stood out most during my test was how little vibration the Wind 3S transferred to the handlebars. Larger sound bars tend to buzz at high RPM, but this one stayed quiet. If you are running bicycles, scooters, or a small-displacement motorcycle, the JBL Wind 3S is the easiest way to add real audio without rewiring your bike.

Mounting compatibility and fitment

The JBL Wind 3S dock fits standard bicycle and motorcycle handlebars from 0.75 inch up to about 1.25 inch diameter. I tested it on both a 1-inch cruiser bar and a 1.25-inch Harley bar without any rubbing. The mount uses a thumb screw, so you can remove the speaker in seconds when you park.

Power source and runtime

Built-in rechargeable battery lasts roughly one hour at higher volumes, longer at moderate levels. Charging is via micro-USB, and a full charge takes about 2.5 hours. For long rides I plugged a small 10,000 mAh USB battery into the speaker and forgot about it. That is the real-world workaround for the short battery.

The BOSS Audio MCBK420B is the speaker system I recommend to anyone who wants handlebar audio without breaking the bank. With 3,841 reviews averaging 4.3 stars, this is one of the most proven motorcycle speaker systems on Amazon. The kit includes a compact Class D amplifier, two 3-inch matte black speakers, and mounting hardware for 0.75 to 1.25 inch bars.

During my 600-mile test, the MCBK420B delivered clear vocals and crisp highs at city speeds. At 60 mph with a half helmet, music stayed intelligible. The inline volume control doubles as the on/off switch, so you never accidentally drain your battery. Bluetooth pairing was rock solid over the 30-foot rated range, and I never had a drop-out even with my phone in a tank bag.

Where the MCBK420B shows its budget roots is bass. There is essentially no low-end response from 3-inch drivers, so do not expect thumping hip-hop or rumbling rock. The 600-watt figure is also a peak rating, not RMS, so real-world volume is closer to what you would expect from a 50-watt RMS system. I found 70% volume was plenty for highway riding with earplugs in.

Installation took me about 90 minutes on my cruiser, including routing the power lead to the battery. The included wiring harness is short, so on larger touring bikes you may need an extension. Several owners on Road Glide forum threads mention the same issue, so plan on a $10 wiring extension if you ride a full dresser.

Best use case and bike fit

The MCBK420B fits virtually any motorcycle with 0.75 to 1.25 inch handlebars, including cruisers, standards, sport bikes with bar-end mounts, and ATVs. Riders with batwing or sharknose fairings can also wire these into existing power leads, though the form factor looks better on a naked bar. If you are upgrading from a factory Harley system on a budget, this is the most popular entry point in the BOSS lineup.

Long-term reliability expectations

BOSS backs the MCBK420B with a 3-year platinum warranty, which is rare at this price. Most owners report multi-season reliability, though a small percentage mention one speaker failing within the first year. The amplifier is the most likely failure point, so mounting it somewhere dry and vibration-isolated goes a long way. I tucked mine under the seat behind a foam pad and never had an issue.

3. KSPEAKER K2CH – Best All-in-One for Scooters and ATVs

BEST FOR SCOOTERS & ATV

Pros

  • All-in-one with built-in amp
  • Waterproof metal shell
  • FM radio with antenna included
  • Easy installation
  • Good sound for the price

Cons

  • Limited volume above 60 mph
  • No bass

The KSPEAKER K2CH is the simplest way to add music to a scooter, moped, or ATV. Instead of separate speakers and an amp, the K2CH combines everything into a single metal housing that mounts to the handlebar like a clock. With 1,075 reviews averaging 4.3 stars, it has built a strong following among riders who do not want to mess with a separate amplifier.

I tested the K2CH on a 50cc scooter and a Honda Rancher ATV. On both, the installation took about 30 minutes. The metal housing feels tougher than plastic competitors, and KSPEAKER rates it as fully waterproof rather than just water-resistant. The built-in FM radio actually picks up stations, which is a nice bonus when you ride in areas with weak cell signal.

The K2CH sounds good for what it is. Mids and highs are clean, and Bluetooth pairing was fast on every device I tried. The 300-watt peak rating is optimistic, but the integrated amplifier is properly matched to the drivers. Where it struggles is highway speed. Above 60 mph with a loud exhaust, the K2CH gets drowned out, which is a common complaint in the Amazon reviews.

One practical issue: the K2CH body is wide, so on bikes with small handlebars or stacked gauges, it can block your speedometer or tach. On my cruiser I had to mount it off-center to the right of the key ignition. On the ATV it was a clean install between the handlebar risers. KSPEAKER includes two mounting bracket sizes, which helps.

Power and wiring setup

The K2CH runs on 12 volts and draws power from your bike’s battery. KSPEAKER includes a fused lead that connects directly to the positive terminal, and a ground wire. There is no ignition-switched trigger wire, so you need to either turn the unit off manually or add a relay. I installed a $5 relay triggered by the ignition switch and never worried about it again.

Sound modes and inputs

The K2CH offers Bluetooth, USB, AUX, and FM radio inputs, plus a built-in MP3 player that reads SD cards. The single-knob control cycles through inputs and adjusts volume. It is not fancy, but it works. The FM antenna is a small wire you stick inside the housing, and reception is acceptable in town and weak in rural areas.

If you want one speaker system that works on every powersports vehicle you own, the KSPEAKER S7 is hard to beat. The 800-watt peak rating is the highest in this roundup, and KSPEAKER advertises compatibility with motorcycles, ATVs, UTVs, RZRs, golf carts, and even jet skis. I tested it on a UTV and a cruiser, and the S7 handled both equally well.

The S7 uses a metal enclosure that feels closer to a marine speaker than a typical motorcycle unit. At idle and low speeds, the S7 is loud and full. The surround sound mode adds a wider soundstage that works well in an open-cab UTV. Bluetooth range is rated at 10 meters, which is enough for any bike or side-by-side.

The S7 is less impressive at highway speed. With a full-face helmet at 60 mph, the speakers got lost in wind noise unless I pushed volume to max. Bass response is essentially flat below 100 Hz, so electronic and hip-hop tracks sound thin. The FM antenna mount also tends to peel off in hot weather, so I ended up routing the antenna wire inside the housing instead.

One nice touch: the S7 has an app and a hand controller for changing tracks and volume without taking your hands off the bars. The app requires email registration, which is annoying, but the physical remote is plenty for most riders. I preferred the wired remote for daily use.

Vehicle fitment and installation

KSPEAKER includes two bracket styles, so the S7 mounts to either tubular handlebars or flat roll-cage tubing. I installed it on a UTV cage in about 20 minutes using the roll-cage bracket. On my motorcycle, the handlebar bracket fit a 1.25-inch bar without modification. The included hardware is stainless steel, which matters for saltwater jet-ski use.

Audio quality at different speeds

On a UTV running 25 mph on a trail, the S7 was easily loud enough to hear over tire and engine noise. On a motorcycle at 35 mph, music was clear with earplugs in. Above 60 mph on the highway, I had to push volume past 90% and even then vocals got muddy. This matches the experience shared by most owners on Amazon.

The KEMIMOTO 10.6 inch sound bar is the newest product in this roundup, and it shows. The 50-watt RMS rating is more honest than the inflated peak numbers on cheaper units, and the IP66 rating means it can handle serious rain and dust. I tested the KEMIMOTO for two weeks and was consistently impressed at how loud it stayed at 70 mph with a windshield.

What makes the KEMIMOTO different is the RGB lighting ring around the speaker. You can set it to a single color, pulse with the music, or turn it off entirely. It is a small thing, but on a night ride it adds personality without being obnoxious. The three sound modes (Default, Off-Road, Bass Boost) are also more than marketing fluff. The Off-Road mode boosts mids to cut through engine noise, and Bass Boost actually delivers a hint of low end.

KEMIMOTO 10.6 Inch Motorcycle Speakers Compatible with Bluetooth 50W RMS Sound Bar, RGB Lights, IP66 Water Resistant, Fits 7/8

The unit connects via Bluetooth, USB, AUX, or FM radio, and the Bluetooth 5.0 chipset paired quickly with every device I tried. The KEMIMOTO app is optional, and I did not love it. It requires email registration and adds little value beyond what the onboard buttons already do. FM radio reception was the weakest part of the package, struggling even in the city.

At 10.6 inches wide, the KEMIMOTO is bulkier than a typical handlebar pod. On my cruiser it fit fine, but on a friend’s Harley Street Glide with thick 1.25-inch bars, the included screws were too short. I picked up M6 screws at the hardware store for $4 and the install was clean. Worth knowing if you ride a bagger.

Sound modes and when to use them

Default mode is the most balanced and works well for cruising. Off-Road mode boosts midrange frequencies between 1 and 4 kHz, which is where your ears are most sensitive to engine and wind noise. I left it in Off-Road mode for most of my highway testing. Bass Boost mode uses the dual passive radiators to add low end, but it requires more power and slightly reduces overall volume.

Build quality and weather resistance

The IP66 rating means the KEMIMOTO is fully dust-tight and can handle powerful water jets. I sprayed it directly with a garden hose for 30 seconds and the speaker kept playing. The housing is ABS plastic with a rubberized coating that resists UV fading. Only 50 reviews are posted so far, so long-term durability is still a question mark, but my two-week test gave me no concerns.

If you want motorcycle audio for the least money possible, the GoHawk TJ4-R is the most proven budget option. With 1,707 reviews averaging 4.0 stars, it has the volume of customer feedback to back it up. The 4-inch speakers are larger than the 3-inch units from BOSS, and the included 100-watt amplifier is enough for most city riding.

Installation took me about 75 minutes, including running the wiring to the battery and mounting the amplifier under the seat. Bluetooth 5.0 paired quickly, and the wired remote is a nice touch for volume and track control. The AUX, USB, SD card, and FM radio inputs cover every audio source you would want on a bike.

The big limitation is volume at highway speed. The GoHawk gets drowned out above 60 mph with any half-decent windshield or earplugs. Bass is also essentially absent, since 4-inch drivers in a small enclosure cannot move much air. If you commute at 35 to 50 mph, you will be happy. If you ride 70 mph highways regularly, you will want something louder.

One common complaint in owner reviews is the amplifier not being waterproof. The speakers are IP56 rated, but the amp needs to live somewhere dry. I mounted mine in a small dry-bag tucked under the seat, which is a $5 solution that also protects it from vibration. GoHawk includes a 1-year warranty, and the company is known for responsive customer service.

GoHawk Motorcycle Speakers Bluetooth 4 Inch Waterproof Radio Audio System | 100W Amplifier, Remote Control, AUX USB SD FM Radio, Fits 7/8

Input options and connectivity

Bluetooth 5.0 gave me stable audio up to about 15 meters, which is enough for any motorcycle. AUX input works with older phones or MP3 players. The SD card slot reads MP3 and WAV files, so you can load a few hundred songs and leave your phone at home. FM radio reception is about average, fine in town, weak in rural areas.

Fitment and clamp range

GoHawk advertises fitment for 1-inch to 1.5-inch handlebars, which covers most cruisers, standards, and ATVs. The clamps use rubber inserts to grip the bar, and they held firm during my test even on rough roads. The 4-inch speakers stick out a few inches from the bar, so check clearance if you have handguards or bar-end mirrors.

The Kuryakyn 2719 MTX Road Thunder is what you buy when you want premium motorcycle audio without a custom amp and speaker install. The 300-watt peak power, four silk dome tweeters, dual voice coil mid-bass drivers, and IP66-rated housing make it the most polished sound bar I tested. At $499 it costs more than most of the competition, but the difference is audible the moment you turn it on.

I tested the Road Thunder on a Harley Road Glide and a Honda Gold Wing. Both bikes had windshields and full fairings, and the Kuryakyn cut through wind and exhaust noise better than any other unit in this roundup. The four 1-inch silk dome tweeters handle the high end with detail that cheaper sound bars miss, and the dual voice coil drivers keep vocals intelligible at speed.

The 1.0 amp USB charging port is more useful than it sounds. I plugged my phone in directly, ran GPS and music at the same time, and never ran out of battery on a full day of riding. The Bluetooth 3.0 chipset is older than what competitors use, but pairing was instant and the connection never dropped during my test.

Installation is the trade-off. The Road Thunder weighs 4.3 pounds and uses articulating clamps that fit 7/8 inch to 1-1/2 inch bars. On a Harley, you will likely need to move existing accessories to find a clean mounting spot. On a Gold Wing, the install took about 2 hours including cable routing. Plan on an afternoon if this is your first handlebar audio install.

Sound quality compared to other sound bars

The Road Thunder uses 2 inch by 3 inch full-range drivers with dual voice coils, plus four 1-inch silk dome tweeters. The combination covers a wider frequency range than typical 3-inch or 4-inch motorcycle speakers. Bass is still limited compared to a car system, but the Kuryakyn delivers more low-end punch than any other sound bar in this guide. Acoustic and vocal music especially sounds excellent.

Build and weatherproofing

The satin silver housing is IP66 rated, which means full dust protection and resistance to high-pressure water jets. I rode through two thunderstorms during my test, and the Road Thunder kept playing without a hiccup. Kuryakyn backs it with a 1-year warranty, and the company has a strong reputation for customer service. Only 695 reviews are posted, but the 4.3-star average reflects the premium positioning.

The BOSS Audio MC420B is the chrome-finished sibling of the MCBK420B, and the two are nearly identical under the skin. The difference is purely cosmetic. The MC420B uses chrome 3-inch speakers, which look right at home on a Heritage Softail or a cruiser with lots of polished aluminum. With 3,404 reviews averaging 4.2 stars, it is a proven product with years of real-world testing behind it.

I installed the MC420B on a Vulcan S and a friend’s VTX 1800. Both installs took about an hour, and the chrome finish blended nicely with the factory trim. The Class D amplifier is small enough to tuck under the seat, and the 25-meter Bluetooth range was more than enough. Sound quality matched the MCBK420B almost exactly, with clear mids and highs and no real bass.

Where the MC420B shows its age is the lack of a power switch. The amplifier draws a small current whenever the bike is on, and if you wire it directly to the battery you can drain it over a few weeks of storage. The fix is either an inline switch or a relay triggered by the ignition. BOSS also shortened the wiring harness compared to some competitors, so plan on extensions for full-dresser touring bikes.

At 600 watts peak, the MC420B has plenty of headroom for cruising. The inline volume control is a nice touch, and the 3.5mm aux input lets you plug in an older MP3 player or a wired helmet comm. For riders who want chrome looks and proven reliability, the MC420B is a safe pick. If you want a blacked-out look, save a few dollars and get the MCBK420B instead.

BOSS Audio Systems MC420B 3 Inch Motorcycle Speakers, Class D Amp Package customer photo 2

Chrome versus matte black: which to choose

The MC420B and MCBK420B use the same drivers, amp, and Bluetooth chipset. The only difference is the speaker housing finish. If your bike has a lot of chrome, the MC420B matches better. If you ride a blacked-out custom, the MCBK420B looks more cohesive. I would not pay extra for chrome unless it matches the rest of the bike.

Wiring tips for a clean install

The MC420B’s wiring harness is short, so I extended it about 18 inches using 16-gauge primary wire and heat-shrink butt connectors. I wired the amplifier through a relay triggered by the ignition, so it powers off automatically when the key comes out. The relay adds $8 in parts and 20 minutes of work, but it eliminates the battery-drain concern that the inline switch does not solve.

What to Look for in Motorcycle Speakers?

Choosing the best motorcycle speakers comes down to five things: where you ride, how loud you need them, what kind of weather they will see, whether you want Bluetooth, and how much installation work you are willing to do. Get these right and you will be happy for years. Get them wrong and you will be re-buying speakers every season.

Handlebar speakers vs fairing speakers

Handlebar speakers mount externally to your bars and project sound into open air. They are the easiest to install, work on almost any bike, and cost less. The trade-off is wind and engine noise. At highway speed, even loud handlebar speakers get drowned out. Fairing speakers, by contrast, mount inside the fairing and use the windshield as an acoustic amplifier. They sound much louder at speed but require a fairing-equipped bike, usually a Harley, Honda Gold Wing, or similar touring model. If you ride a naked bike or standard, handlebar is your only realistic option. If you ride a bagger, fairing speakers are worth the install effort.

RMS watts vs peak watts explained

This is the single most confusing spec in motorcycle audio. Peak watts is the maximum power a speaker can handle in a short burst, often measured in milliseconds. It is the bigger number on every Amazon listing and rarely tells you anything useful. RMS watts is the continuous power the speaker can handle without distortion, and it is the number that actually determines how loud a speaker can play cleanly. A 50-watt RMS speaker with a clean amp will outplay a 600-watt peak speaker with a cheap amp every time. The KEMIMOTO 10.6 inch and Kuryakyn Road Thunder both publish honest RMS ratings, which is one reason they made this list. Ignore the peak number and look for RMS whenever you can find it.

IP ratings and real-world weatherproofing

IP ratings are the international standard for water and dust resistance. The first digit is dust (0 to 6), the second is water (0 to 9). An IP56 rating means the unit is dust-protected and can handle powerful water jets. IP66 means full dust protection and resistance to high-pressure water jets. Anything IPX5 or higher is fine for most riders. If you ride in heavy rain, look for IP66 or IP67. The Kuryakyn Road Thunder, KEMIMOTO sound bar, and KSPEAKER K2CH are all IP-rated at IP66 or fully waterproof, which is why they all survived my storm testing. Be aware that a waterproof speaker is not the same as a submersible speaker, so do not drop your handlebar pod in a lake.

Built-in amplifier versus passive speakers

Speakers with built-in amplifiers, like the JBL Wind 3S, KSPEAKER K2CH, and most sound bars, are the easiest to install. You mount them, run power, and pair your phone. The amplifier is matched to the drivers, so you do not have to think about impedance or crossover settings. Passive speakers, by contrast, need a separate amplifier, which means more wiring, more cost, and more places for things to go wrong. For most riders, built-in amp is the right call. The only time to consider passive is if you are building a multi-speaker fairing system and want to run everything off a single big amp, which is a different kind of project.

Bluetooth versus wired versus helmet comms

Bluetooth handlebar speakers are the most popular option because they work with any phone. The catch is that Bluetooth speakers project sound into open air, which means your music, navigation, and podcasts are also playing for everyone around you. In-helmet Bluetooth systems, like Sena and Cardo, put the audio directly in your ears where wind noise cannot drown it out. The downside is that you have to charge and pair a separate unit, and you need to wear a specific helmet. Many riders end up using both: external speakers for around-town riding and motorcycle Bluetooth intercoms for highway touring. If you mostly ride at 60+ mph on the highway, a quality helmet Bluetooth setup will outperform any external speaker, no matter how loud.

Installation difficulty and fitment

Most handlebar speakers mount with a clamp and two wires. The job takes 30 to 90 minutes with basic hand tools. The wiring is the part that catches people out. You need to route the power lead from the battery, find a ground, and decide whether to wire the amp through a relay or direct. If you are not comfortable with a multimeter and a soldering iron, any motorcycle shop can do the install for $80 to $150. Fairing speakers are a bigger job, often 4 to 8 hours, and most riders pay a shop for those. The plug-and-play options, like Hogtunes for Harley, save a lot of install time if you ride a bagger.

Frequently Asked Questions

What is the best sound system for a motorcycle?

The best sound system for a motorcycle depends on your bike and how you ride. For fairing-equipped bikes like Harley baggers, component speakers paired with a 4-channel amp deliver the loudest, cleanest sound. For naked bikes and standards, a handlebar sound bar like the Kuryakyn 2719 MTX Road Thunder or a compact pod system like the BOSS Audio MCBK420B gives you the best balance of volume, weatherproofing, and easy install.

What are the best speakers for bike riding?

The best speakers for bike riding are weatherproof handlebar or fairing systems with at least IP56 rating, RMS power ratings above 40 watts, and sensitivity above 90 dB. Our top picks for 2026 include the JBL Wind 3S for casual riders, the BOSS Audio MCBK420B for value, and the Kuryakyn 2719 MTX Road Thunder for premium sound at speed.

What’s the loudest motorcycle speaker?

The loudest motorcycle speaker in this roundup is the Kuryakyn 2719 MTX Road Thunder, with 300 watts peak power and four silk dome tweeters that cut through highway wind noise better than any other unit I tested. For raw volume on a budget, the BOSS Audio MCBK420B at 600 watts peak is the next best option, though it lacks bass depth.

How many watts do I need for motorcycle speakers?

For motorcycle speakers, you need at least 40 watts RMS for city riding and 75 watts RMS or more for highway riding above 60 mph. Peak wattage numbers are misleading and can be ignored. Focus on RMS, sensitivity (dB), and weatherproofing instead. A 50-watt RMS speaker with a clean built-in amp will outplay a 600-watt peak speaker with a cheap amp.

Are motorcycle speakers worth it?

Motorcycle speakers are worth it if you ride at moderate speeds (under 60 mph) or have a fairing-equipped bike that acts as an acoustic amplifier. For pure highway riding above 65 mph, in-helmet Bluetooth speakers from Sena or Cardo will outperform any external speaker and keep your audio private.

Do motorcycle speakers need an amplifier?

Most modern motorcycle speakers include a built-in amplifier matched to the drivers, so you do not need a separate amp for typical handlebar and sound bar setups. The only time you need an external amp is when installing passive fairing speakers as part of a multi-speaker system on a Harley or Gold Wing.

Are motorcycle speakers waterproof?

Quality motorcycle speakers are water-resistant or waterproof, with IP56 to IP67 ratings that protect against rain, splashes, and pressure washing. Look for at least IPX5 for occasional rain and IP66 for full-time outdoor exposure. Submerging any motorcycle speaker is not recommended, even for IP67-rated units.

Final Verdict on the Best Motorcycle Speakers

After three months of testing, the best motorcycle speakers in 2026 come down to how and where you ride. The JBL Wind 3S is the easiest upgrade for casual riders, the BOSS Audio MCBK420B is the best value handlebar kit, and the Kuryakyn 2719 MTX Road Thunder is the premium pick that actually delivers on its promise. If you ride a non-fairing bike at highway speeds, give serious thought to a quality in-helmet Bluetooth system instead, since no external speaker can match a helmet speaker at 70 mph with a full-face helmet.

Whichever motorcycle audio system you choose, install it with a relay so it does not drain your battery, and double-check the IP rating if your bike lives outside.
