The 6 Best Compact Marine amps (2023 reviews)

It comes with this Kenwood amp and they sound fantastic. That little amp is so loud and pulls such a small amount of power for the volume of the music that would just leave it the same size as what it comes with. It’s easy enough to run a separate wire with dedicated power to the amp. The amp tucks away inside the dash behind the new radio and is held in place by the provided zip ties. It cranks while going at just about any speed.

This amp has to connect to wires from a speaker which then connect to a radio or Bluetooth player. The Sound quality is great and the size is perfect for the use. It does get hot rather quickly.
