What to Look for in Choosing a Motorcycle Amp


The size of your amplifier is one of the first things you want to pay attention to. The last thing you probably want is a large amp taking up a lot of valuable space on your vehicle.

For this reason, check the dimensions and whether the size works for your needs and preferences. Amps come in various sizes, meaning that there’s at least one that fits you out there.

As you probably noticed, most models are relatively compact, but some are still smaller than others. These are typically easier to fit within the vehicle without taking up too much space.

Power Rating

Power rating is another critical factor to consider, making sure that the amp has the same output power as the speakers.

Failing to match the amp and speakers often leads to overpowered or underpowered speakers. As a result, you’ll get less than impressive performance.

Less power often means distortion and unclear sound. On the other hand, an overpowered amp can blow the speakers out.

Check the RMS rating of the amp and compare it with the speakers’ power requirements to get the best match. This will help you to get a clear sound and overall best performance.

Number of Channels

Motorcycle amplifiers have a different number of channels. The number of channels means the number of speakers the amp can adequately power.

In other words, a two-channel amplifier can only power two speakers, while a three-channel amp can power three speakers. A mono-channel amp can only power one speaker.

This is quite basic, and there are very few ways to change the way these amps operate. However, some models allow you to bridge channels into one, which often results in better sound output.

Again, many different kinds are available, meaning that there’s one for everyone.

Ease of Use and Installation

Motorcycle amplifiers are relatively easy to install and use. However, this often depends on the exact type and model you go for.

The ease of installation usually depends on your skills and whether the product came with any instructions. If not, you might want to look for some online or have a professional install it for you.

Another thing that helps with ease of installation is the hardware included. Check if your amp of choice comes with everything you need to install it.

Most models are relatively easy to use once installed, featuring basic volume controls and Bluetooth.

Weatherproofing and Durability

Both durability and weatherproofing are critical when choosing a motorcycle amplifier. Chances are you’ll use the amp in variable weather and rough riding conditions.

If so, you want one that can endure an occasional water splash, rain, snow, dust, and possibly even a drop on the ground. Think about the conditions you usually ride in and ensure that your amp of choice can handle that.

Most models are weatherproof and water-resistant, featuring a sealed design that can handle extreme weather. They’re made from durable materials that can endure harsh riding conditions without damage.


Filters are something you won’t hear about often, although they’re quite critical in your choice. As you may have noticed, amps have low and high pass filters.

Low pass filters are meant to help cancel high frequencies. On the other hand, high pass filters do the exact opposite.

As a result, the two types deliver clear and smooth sound regardless of the riding conditions. This is especially important when riding at high speeds when the road noise is at its highest.

It’s a critical factor to think about if you’re looking for a quality amplifier to deliver the best sound.


Some amps are wired, while others are wireless. Choosing between the two is often a matter of preference since it’s difficult to tell whether one type works better than the other.

Still, having a wireless amp makes some difference in aesthetic. It eliminates the need for wires, making your bike look neater and cleaner.

If this is what you aim for, look for a model with Bluetooth connectivity. Many of the latest amplifiers have built-in Bluetooth, allowing riders to enjoy music without any wires. (See a selection of bluetooth headsets here.)

It’s a well-known technology you probably know how to use, so these aren’t much more complicated than wired ones.


Warranty is always essential to check when buying motorcycle equipment. Luckily, reputable brands always offer long-lasting warranties that cover damage caused by faulty manufacturing.

However, you should take the time to read the deal before purchasing a product. It helps to understand what exactly it covers in case you ever have to claim it.

Most brands don’t cover for damage caused by misuse, normal wear and tear, and neglect. You’re unlikely to get anything out of it if you’ve used the amp inadequately, so make sure to install and use it as explained and recommended by the manufacturer.


Motorcycle amplifiers come at different prices, making it easy to find one for any budget. However, it would help if you considered your budget before you start the search.

In most cases, having an idea of how much money you’re willing to spend makes it easier to pick one among as many. It helps to narrow your list of options so that you don’t waste any time.

Still, take the time to think about other buying factors we talked about. Things like durability, power, number of channels, and waterproofness are often more important than the price.



Much like any Bluetooth device, a motorcycle amp with Bluetooth connectivity doesn’t require wires for connection. It can be used with any Bluetooth-enabled device such as your phone and mp3 player to listen to music or control the radio.

It looks pretty clean once installed since there aren’t any wires spread across your bike.


As the name suggests, wired amplifiers do require wires for connection. Although this can be somewhat inconvenient at first, most people are quick to get used to it.

A wired connection might not look as clean, but it has other benefits. It’s often more stable than a Bluetooth connection.

Why You Should Own a Mini Motorcycle Amplifier


Although many touring bikes already have a sound system, these are usually not so great. Many riders replace their stock sound system almost immediately after buying a motorcycle.

Upgrading your amp and speakers is relatively simple and doesn’t have to be expensive, depending on the particular model you go for.

Enjoyable Music

Road and engine noise can be quite tiring after a while, even for people who usually don’t mind it. This is where a quality amplifier can come to the rescue, making it easy to listen to your favorite tunes while riding.

It enables you to listen to music and ensures that the sound quality is at a high.

Stronger Audio Signals

A rich sound is only achievable with a quality motorcycle amplifier. It’s something not many amps can deliver, especially if we’re talking about the poor-quality stock ones.

Best amps enhance your audio system, delivering a more powerful sound regardless of the riding conditions.

How and Where to Install Your Amp

The first thing to remember is that you can install an amplifier anywhere on your motorcycle. Find a place that you can easily access, making sure that it doesn’t block its audio inputs.

Most people install it on their handlebars, saddlebag, tank bag, under the seat, or the headlight. The choice typically depends on the amplifier’s overall size and how much space you have to work with.

Also, think about if your amp has installation hardware. If so, consider where that type of mounting would work the best.

The best of all is that you can test several areas since most amps are easy to mount and remove.

Frequently Asked Questions

What are the power requirements of motorcycle amps?

Power requirements differ from model to model. You might want to check the amp’s RMS power rating before purchasing it to ensure it matches your speakers.

Ensure that it delivers enough power to feed the speakers and other components of the sound system.

Are car amps suitable for motorcycles?

Although car amps are similar to those meant for motorcycles, you should avoid using one on your bike. Those meant for cars operate at high loads and will most definitely drain your bike’s battery quickly.

It might run for a while, but you’ll soon notice engine failure and dimmer lights, among other issues.

Does it need to be wired in the battery to work?

This depends on the particular model you go for. Some don’t require any wiring, while others are meant to be wired to the battery or deck power supply.

In most cases, either type is acceptable as long as it fits your needs and preferences.


A quality amplifier makes all the difference in how you enjoy music while riding. It can help deliver clear and loud sound without distortion regardless of your riding style or the weather conditions.
