Selection Criteria

When searching for the right product, here are certain features you should be interested in seeing:

The number of channels: The general rule is that the higher the number of channels an amp offers, the stronger it is in power multiple speakers. Keep in mind also that the number of channels that is supported by the marine amplifier must be equal to or greater than the number of speakers you are powering.

So make sure you check the number of channels when reading the product description.

RMS rating: This is the measure of continuous power that a marine amp can handle at its best. The higher the RMS rating, the better the quality of sound it will produce. We recommend you choose a marine amp with optimal RMS rating as this will be the best for your stereo.

It is also vital to check the ratings of your stereo system. It is often specified on the package what the R.M.S rating of any compatible amplifier should be.

Construction: If your amplifier will serve you for long on the seat, it must be waterproof, rustproof, and sturdy. Water can damage below par materials easily, so it is also good to be sure the amp is not made from cheap materials.

Since it may eventually be subject to harsh weather, it may be necessary to get one that is not too big so it can fit in a compartment of the boat. This way you can get the best value out of it.

Equalizers and Filters: if you like to play around the sounds coming from your amp, you should also check if this feature is available. With it, you can manually set the bass and treble. This feature allows you to get an overall premium experience. The filter will help you get rid of any distortion to the sounds produced.
