How to Choose the Best Motorcycle Amplifier in 2022
When looking for an amplifier for your motorcycle, there are several factors you should keep in mind in order to choose the perfect one. These factors are power, sound quality, weatherproofing, and size. Make sure to take all of these into consideration before making your final decision.
Size
You should keep in mind the size of the motorcycle amp when you are looking for one. The size of the amp will determine how much space it will take up in your motorcycle.
Power
You should focus on an amp’s peak power, or maximum output when choosing one for your bike. The continuous power an amp can generate is its RMS power rating. Be careful of amps with high power ratings, as they might be inflated. To avoid this, choose an amp that is certified by the CEA.
Channels
The motorcycle amplifiers are organized based on how many channels they can power. “Channels” refers to the number of speakers the amp can handle. If your audio system has one speaker or a subwoofer, you need a mono-channel amp.
A two-channel amplifier can power up to 2 speakers, a three-channel amp can handle 3 speakers, and so on. Some amplifiers let you bridge channels into one, which creates better sound output for multiple speakers.
