Best For Icechest Stereo: Pyle hydra Marine Amplifier

Buy on Amazon

The pyle hydra marine amplifier is capable of outshining several other amp featured in this list in overall features for the price point. This is for a boat where you are putting this under a seat that wouldn't normally be exposed (directly) to getting splashed or drenched, this is a good choice. It is built with sturdy quality metal and other materials. It is compact, and splash proof, not waterproof. It comes with the cable for using the High Input / speaker level inputs, a spare fuse, and mounting screws. The amp can only handle 240 watts of speaker at 4 to 8 ohms impedance.

It's easy to install, even though it's marketed as a marine amp, it works great in the car if you don't need a giant amp. The sound quality is excellent and there's plenty of power to overcome the road noise inherent in a Wrangler. These are used on the back porch by the pool with some tiny marine speakers and it is awesome sound even if you don’t count how inexpensive they are.

This amplifier is rated for 50 watts RMS at 14.4 volts per CEA 2006 compliance. It allows the amplifier to be extremely compact. At normal volume levels, it is cool to the touch and only gets hot when you really push it hard.
