Where To Install A Motorcycle Amplifier?

One of the most asked questions by bikers is where to install a motorcycle amplifier.

You need to know that there’s no specific place for installing an amp on your motorcycle.

Things To Look For Before Buying A Motorcycle Amplifier:

Choosing the perfect amp for your motorcycle doesn’t have to be hard, especially when you know exactly what to look for in an amplifier.

Below, we outline the TOP factors that define an ideal amp for your bike:

Number of channels

As you have seen in our motorcycle amplifier reviews list up there, motorcycle amps are categorized based on the number of channels.

For starters, “channels” simply means the discrete speakers a given can adequately power.

If your audio system is made up of only one speaker or a subwoofer, then you’d want to look for a mono-channel amp. A two-channel amp will power up to 2 speakers, 3 channels for 3 speakers, and so on.

While still at it, keep in mind that some amps allow you to bridge channels into one to form better sound outputs for multiple speakers.


Another important thing to keep in mind when looking for a motorcycle amp is its physical size.

Different amps out there come in different sizes as you have seen in our motorcycle amp reviews above.

Although most of the feature small and compact designs, we advise you to double-check to ensure the specific model you pick will fit in the available space in your motorcycle.

Power rating

You’ll also need to ensure that the amp you’re purchasing has an output power that matches that of your system’s speakers.

Why is this important?

Most bikers don’t know this, but not matching the amp and speakers can lead to underpowered or overpowered speakers.

If you get an amp that supplies your speakers with less power, then they’ll output weak, distorted, and unclear sounds.

And if you get an overpowered amp, it can blow out your speakers. This is especially true if the amp output is far much greater than that of your speakers.

To get the perfect match for amp and speakers, check the RMS rating of the amp (which indicates the consistent power the amp can provide) to and compare it with the total power requirements of your speakers.

Pro TIP: Not just speakers, ensure you get an amp that’s compatible with your entire motorcycle audio system. Using the wrong amp will not give you any improvements. Look for amps that feature extended frequency responses as well as low deviations. Also, check if the amp manufacturer lists its product’s THD (distortion). The lower the THD number the better.

Additional features:

  • Weatherproofing: if you plan to ride your motorcycle in extreme weather, consider an amp that comes with a weatherproof design.
  • Ease of installation: an amp that comes with all the necessary installation hardware plus user manual will be much easier to install.
  • Bluetooth connectivity: if you don’t want anything to do with wires, then investing in an amp with wireless Bluetooth technology is the way to go.
  • Low/high pass filters: low pass filter helps cancel higher frequencies. The high pass filter does the opposite. The results in a smoother and clearer sound output.
  • Warranty: a replacement warranty will help safeguard your new investment in case things you turn it one day, and it fails to work.

Frequently Asked Questions:

1. What’s the work of a motorcycle amplifier?

A motorcycle amplifier is typically an electronic device designed to boost (or amplify) the signals from your audio input devices such as radio, CD player, mp3 player, and more.

To do this, the amplifier alters the amplitude of the audio signal to output more powerful audio signals. And yes, you guessed it right, this translates to more powerful music.

2. How much power do I need on the motorcycle amplifier?

The power requirements for these devices vary from model to model. This explains why you’ll find different models featuring different power ratings.

We advise you to pay close attention to the RMS power rating of the amplifier you plan to purchase. This indicates the average measure of the amount of power the amp can consistently output.

The RMS value should match or be very close to your bike speakers power requirements.

Overall, make sure you the amplifier you choose delivers an adequate amount of power to feed all the components of your sound system.

3. Can I use a car audio amplifier on my motorcycle?

No, it’s not a good idea to use a car amp on your motorcycle. This is because the car-specific amp is designed to operate at extremely high loads, and can drain your motorcycle battery really fast.

Sooner, you might start experiencing issues like dimmer lights, engine failure, and more.

We STRONGLY urge you to stick to motorcycle-specific amplifiers as they draw low loads from the battery, so they won’t strain your battery—enabling it to last longer.

Final Verdict

Riding your motorcycle for long trips while listening to your favorite music is a priceless experience. The music nourishes your soul, and give you the zeal to finish your journey.

Investing in the best motorcycle amplifier goes hand in hand in ensuring an entertaining “musical” journey. A good amp for your bike boosts the power and quality of the sound signals coming from your audio input devices—translating to more powerful music output.

Never take on a long stretch of roads again while listening to the dull sound of your engine.

Order one of the hottest amps we’ve outlined above to make your trips more memorable and addictive!
