Buying Guide of Best Motorcycle Amplifier

Choosing a Bluetooth motorcycle amp for your bike does not have to be a tiring process, especially if you know what you are looking for. Below I have looked at some of the features or factors that you should consider when choosing an amplifier for your motorbike.    

1. Number of Channels

You might have noticed from the above review of the top ten motorcycle amps that these systems come with variable channels. If you are a novice, “channels” are the number of speakers an amplifier can power successfully.

Therefore, if your audio source is made of a single subwoofer or speaker, then you need to consider choosing a mono-channel amp. A 2-channel amplifier can power a maximum of two speakers, a 3-channel one, three speakers, and so on. 

Also, note that some amplifiers can let you bridge channels to create a single channel that produces better music for different speakers.

2. Size

Another feature that you should consider is the physical size of the amplifier you want to buy. You can get a mini amp for motorcycle or even whatever the size you want – most of the products in our review comes in small sizes.

With that said, I would recommend you double-check the size to make sure that the amp you choose fits your needs. Don’t just pick a gear because it is listed as a compact and small unit.

3. Power Rating

You also need to check at the power rating of the amplifier you intend to buy and make sure that it matches your speakers. Not matching the speakers with the amp can result in overpowered or underpowered speakers.  

For instance, if you select an amplifier that supplies the speakers with more power, they might blow out. On the other hand, less power can mean that you get weak, unclear, and distorted sounds.

Check the RMS rating before you settle for a specific amp to ensure that you get the ideal match for speakers and the amp. The RMS rating shows the amount of power the amp can provide consistently.

Some things to note:

  • Make sure that the amplifier is compatible with your motorbike audio system – not just the speakers.
  • Go for an amp with low deviations and extended frequency responses.
  • Check if the amplifier is listed as THD (distortion) – the lower, the better.

4. Additional Features

Here are some of the other things that you should consider when choosing your motorcycle amplifier.

  • Weatherproofing – Go for a model that has a weatherproof design to ensure that you use it in harsh conditions.
  • Easy to install – Choose a system that you can quickly put in place without needing additional tools or professional help. It should also come with an installation manual.
  • Bluetooth connectivity – A motorcycle amplifier Bluetooth is a must-have feature if you don’t want to connect wires.    
  • High/low pass filter – Low pass filter cancels higher frequencies. The top filter cancels lower rates. That gives you a clearer and smoother sound output.
  • Warranty – It helps to safeguard your money in case the amp stops functioning.
