Characteristics of Our Favorite Amplifiers

The following considerations are crucial when you shop for motorcycle amplifiers:

Output Power

Pay attention to the Root Mean Square or RMS ratings of any amp you want to buy. It indicates the continuous maximum power the amp can generate. These numbers give you the true picture of what the unit can handle.

While you are at it, keep an eye out for an amp with a Consumer Electronics Association’s (CEA) certification. That’s a surefire way to know that the output power rating on the unit is genuine.

Unit Size

An amplifier that sticks out because it is too big can ruin your bike’s aesthetics. You don’t want to force a unit onto your motorcycle. Therefore, make sure you choose a model with the correct physical dimension to match your vehicle.

Weatherproof Feature

Unlike cars, motorcycles don’t usually have protective coverings. For this reason, your best bet is to invest in a weatherproof amplifier that can resist the harsh effects of the elements.

It doesn’t matter whether you think you won’t ride in the rain or snow. An amp’s performance can still be adversely affected even in sunny weather. Besides, a weatherproof feature won’t burn a hole in your wallet.

Review of the Best Motorcycle Amplifiers

Here are our top picks of the best motorcycle amplifiers that can help you enjoy your rides even more.

Best Overall:
Jensen JAHD240 80W 2-Channel Universal Amplifier


  • Red LED power indicator
  • Very affordable amplifier with impressive sound performance
  • Corrosion-resistant, waterproof, suitable for use in all weather
  • Two-channel audio amplifier, compact design, can connect to MP3 and iPods
  • Universal fit, suitable for use on all types of vehicles, including motorcycles, cars, and boats


  • No wireless connectivity
  • Not a popular amp among riders

What Recent Buyers Report

Although Jensen’s 2-channel universal amplifier has been in the market for a while, it is not a widely bought product, at least not on popular online stores. However, nearly all the buyers have the same positive story about the amp. It works incredibly well, producing nice sounds for its size.

Why it Stands Out to Us

We choose this amplifier as our overall best product because it is one of the toughest units available. It can withstand just about any adventure you plan to undertake, regardless of the weather.

Jensen engineered this amp to be a compact unit. Regardless of its small size, it delivers remarkable sounds, thanks to the 8-ohm, 2 x 40W maximum power. It also features RCA audio input connectors and an LED power indicator that lets you know it is on.

The amp also allows you to enjoy music from your MP3 device or iPod by connecting it using an optional Jport input jack.

Bottom Line

If you are in the market for a decent amplifier at an affordable price, you might want to take a look at this option. It is a compact unit with amazing sound production and fits into nearly all motorcycle models.

Hogtunes 225 Watt Amplifier Kit


  • Includes all hardware and wiring for installation
  • Can accommodate any future software upgrades
  • Expansion port allows for additional amplifier or extra speakers
  • Two-channel, 100% plug and play model, excellent for newer touring motorcycles
  • Unit covered by top-of-the-line warranty, three years on amplifier and years on speakers


  • Very expensive model
  • Does not fit all motorcycles

What Recent Buyers Report

Many buyers are happy with the overall performance of this plug-n-play amplifier. They find the sound output to be outstanding even on motorcycles with thunderous exhausts and at interstate speeds. The unit is pretty straightforward to install, and users who had minor issues say the brand’s customer service is exceptional.

Why it Stands Out to Us

This is an excellent amplifier kit for Harley touring motorcycles. We think the most outstanding thing about this unit is that it doesn’t strain your battery or charging system while it delivers maximum output.

You don’t need to re-flash your radio to use the Hogtunes 225 amplifier. It works with existing radios and can accommodate future software changes.

You don’t have to spend extra cash on buying wires, cables, or any other piece of hardware. Everything you need to install this unit comes in the package.

Plus, it comes with a specific mounting plate for your bike’s model.

Bottom Line

If you own a Harley Davidson, this might be the amplifier for your bike, as the product only fits bikes from this brand, particularly models from 2014. It is the most expensive unit on this list, but it doesn’t disappoint.

Best for the Money:
Kenwood 2156568

Kenwood 2156568 KAC-M1804 Compact 4-Channel Amplifier


  • Affordable option compared to other brands
  • Excellent build quality, compact design  with four channels
  • Extruded aluminum heat sink design keeps unit from overheating
  • Power-efficient model with high output rating for better sound quality
  • Conformal coated circuit offers extra protection for use in high humid areas


  • Fragile channel output wires
  • Bluetooth connectivity not supported

What Recent Buyers Report

Buyers love this product from Kenwood because it works great for motorcycle use and other applications. Many users appreciate the fact that the unit is small enough to fit into tight spaces. According to customers, the amp offers great value for money and puts out decent power for its size.

Why it Stands Out to Us

Kenwood’s amplifier is a compact four-channel unit that delivers an outstanding 400 watts power output.

But that’s not all. It has an RMS power rating of 4 ohms, providing 45 watts of power to each of its channels. All this translates into louder and superior sound quality.

Connecting to external speakers is not an issue with this amp because it comes with a complete wiring kit.

Kenwood engineered this model with an aluminum heat sink that prevents the unit from overheating even in extreme conditions and continuous use. This is one amp that won’t disappoint as far as performance goes.

Bottom Line

Kenwood is a household name when it comes to electronics. Choosing this product means you are buying an amp with lots of reliability. However, it doesn’t have Bluetooth capability, so consider this option if that’s not a deal-breaker for you.

Best Motorcycle Amplifier Bluetooth:
velex 8541737301

Water Resistant Bluetooth Marine 4 Channel Class A/B Amplifier Media Stereo on Boats UTV ATV Golf Carts and Cars

What Recent Buyers Report

There is a generally positive feel from buyers about this smallish motorcycle amplifier. Many happy users say it works as expected and offers lots of functionality, such as wireless connectivity, in addition to great sound output. Some customers point out its lack of volume dial, which prevents quick volume adjustment.

Why it Stands Out to Us

Many amplifiers have Bluetooth functionality, but Velex stands out with its additional performance features, such as a USB audio input. There are only a few other models in the market that offer this function.

Its wireless connectivity is topnotch, allowing you to seamlessly play your favorite tracks from your smartphone and other devices.

The unit comes complete with digital remote control that lets you operate the amp more conveniently. You can turn the device on or off, switch tracks, and even adjust the volume from the compact remote.

The amp is layered with a conformal coating for efficient heat dissipation.

Bottom Line

Velex is an excellent choice if you prefer an amp with wireless connectivity. It is packed with tons of impressive features lacking in many similar models. This amp will last for a long time due to its stainless steel construction.

Best Motorcycle Amplifier 4 Channel:

What Recent Buyers Report

This is the amplifier of choice for many riders and for good reason. It delivers a big bang with its impressive four-channels. Buyers say this is by far the smoothest and cleanest subwoofer amplifier they have used. It might be slightly expensive, but customers say it is worth the price.

Why it Stands Out to Us

With a peak power of 800 watts, this four-channel amplifier delivers enough power to your speakers for an amazing sound experience. This is a CEA compliant model, so you can be sure that the ratings are authentic.

One notable feature of this model is the three-way circuit protection. It keeps the unit safe from overload, shorts and offers thermal protection, all of which ensure the longevity of the amplifier.

One other reason we think this is a great amp is its size. You can conceal the unit in small spaces on your bike, thanks to its micro class D compact design.

Bottom Line

If you are looking to get all your motorcycle speakers jamming your favorite track, you may as well consider this four-channel full range amp from NVX. It packs enough power for any type of subwoofer you may have on your bike.

Best Small Motorcycle Amplifier:

It fits many different vehicles, including bikes, RVs, and off-road vehicles, making it a widely used amplifier. Users appreciate its remarkable power output and the capacity to work with four speakers. Overall, many people find the model exceptional.

Why it Stands Out to Us

Soundstream didn’t call this amp a stealth unit for nothing. It is one of the tiniest models in the market that offer excellent improvement to sound quality.

The unit measures 7.75” L x 3.0” W x 1.5” H and weighs a mere 1.9 pounds, making it small enough to fit into tight spaces on your motorcycle.

Apart from the compact build, it has an outstanding 400 watts power output with four channels. This gives you the flexibility to use the amp with four speakers for an amazing music experience every single time.

Installation is a breeze, and the amp is highly affordable.

Bottom Line

Consider this option if you want a motorcycle amp that won’t stick out like a sore thumb. But size is not the only thing going for this model. You’ll enjoy the awesome output in 4-ohm bridge mode. Simply worth buying!

Pyle’s amplifier strikes a balance between performance and affordability. First of all, it is completely waterproof, rust-resistant, and weatherproof, so you can enjoy good music while riding in the rain or through wet paths.

You can stream your favorite music with Bluetooth connectivity from your smartphone or other modern devices. The amp also supports USB flash and SD memory card readers, allowing you to play various file formats, including MP3, WMA, and WAV.

Bottom Line

Riders who want to have complete control of every tone of their favorite music can do that with the adjustable equalizer control in this unit. The Pyle PFMRA340BB.5 is an excellent choice for those who ride mostly in wet conditions.

Advantages of Investing in a Quality Amp

Improved Sound Quality

An amplifier boosts audio signals, resulting in better sound quality. The technology is necessary to drive your sound system if you want to enjoy your favorite music over external speakers.

Whether you are playing music from an MP3 device, a USB, or a smartphone, an amplifier produces pleasant sounds. Even at a much higher volume, you won’t notice sound distortions. Instead, you will get crispier and more detailed vocals, impactful bass guitars and drums, and overall dynamic sounds.

Enjoy Your Favorite Music On the Go

Of course, riders who are music lovers don’t have to endure boredom just because they are on their motorcycles. It’s like combining two of your favorite things – your beautiful bike and your best tunes. This is the perfect combo for an enjoyable road trip.

Upgrade Your Motorcycle

Many motorcycles are fitted with some sort of audio system, but they are usually not what you’ll call the best sound systems. Upgrading these will improve the value of your motorcycle.

Also, consider installing better speakers because they top the list of vital components in any audio system. Even the best amp will still produce second-rate sounds at best if the speakers are mediocre.

Motorcycle Amp Safety Considerations

Listening to music during rides can be fun, but you want to stay safe. Consider these safety tips.

Install an Amplifier With the Correct Power Rating

First, make sure to install an amplifier that works for motorcycles. You don’t want to drain your bike’s battery with a unit that draws too much power.

Watch the Road

Don’t allow yourself to get carried away by your favorite music while riding your bike. Keep your eyes on the road, especially when going into bends.

Consider turning down the volume of your music if it affects your concentration. Although it feels great to enjoy good music during a ride, you want to arrive safely at your destination.

Stay Within Acceptable Volume Limits

While it is legal (in most parts of the world) to install a sound system on your vehicle that can get very loud, it can be illegal to use it on its loudest volume.

You can potentially get into some trouble with your local law if the music on your motorcycle is so loud that it adversely affects other road users. It is also highly risky if your music is so loud you can’t hear honks from other riders and drivers.

Motorcycle Amp Installation 

Installing an amplifier on your motorbike is not rocket science. However, you need to understand how to properly do it so you won’t cause any unintended damage. As long as you choose the right amp for a motorcycle, you shouldn’t have any problem.

Follow these simple steps to install your new motorcycle amp.

1. First, remove your bike’s seat to access the battery. Disconnect the negative terminal to protect you from possible shocks and prevent shorts from your electronics.

2. Decide on an easy-to-access spot on your motorcycle where you will mount the amplifier. Some common locations include on top of the stereo or right next to it and under the seat. Whichever area you choose, use zip ties, mount plat brackets, or some other hardware to secure the unit.

3.  Connect the amplifier to all the necessary components beginning with the remote power and RCA cables. Run these to the stereo and wire the power cable to the battery’s positive terminal. Next, run the ground wire to a neutral point.

4. Test out the amplifier before reassembling and cleaning up.

Amplifiers usually come with manuals. Be sure to refer to this for your specific model’s wiring diagram and instructions.


Investing in a good-quality motorcycle amplifier can improve your overall bike riding experience. We strongly suggest that you carefully give thoughts to the qualities of a good unit, as discussed in the early parts of this article. Also, don’t forget the safety considerations for using an amplifier on your bike.

Do More Powerful Amplifiers Sound Better?

Yes, more powerful amplifiers produce better sound quality. Your ear can differentiate between the sounds from two speakers of different capacities, just as it can hear and notice the difference between a cheap amp and a high-quality option. It makes a lot of sense to invest in more powerful units.

Where Should I Mount My Motorcycle Amp?

This depends on the amount of room on your motorcycle. You can install the amplifier on the tank bag or handlebar if it can nicely fit in there. Whatever spot you choose to place it, make sure you can easily access and connect the unit with your audio system.

How Much is a Motorcycle Amplifier?

Motorcycle amplifiers typically don’t cost an arm and a leg. The price can range anywhere from $70 to $350 and even more. One thing is for sure with these units; you get what you pay for. Generally, cheaper models cost less, but they are not as powerful as high-end options.
