Best Overall: Boss Audio systems cooler radio

Buy on Amazon

Here, we present amplifier that manages to win our hearts. It's the boss audio systems cooler radio and it's widely considered as one of all-around great amplifier you can buy. The secret is to mount your speakers where you take full advantage of the bass vibration through the fiberglass body of your boat. It still works perfect and if you know how to work an equalizer, the sound is great. It comes with wiring, unless you plan to run hot wire and ground to another source area where you should not need old wiring, the speaker length of where you install speakers will determine whether you need extra wiring. The key is to get a very solid ground.

The Controller only has 2 wires for hot and ground. It is ear piercingly loud plus comes with a bluetooth remote. The amp is small so easy to hide and the sound is perfect with 4 speakers.

Best With All Bluetooth devices: Pyle Small Marine Amplifier

Buy on Amazon

The pyle small marine amplifier should be able to handle its purpose and duties with ease. This little amp is all you would need for an atv or cooler radio. It is built with Bluetooth 3.0 connectivity that has a wireless range of 30+ feet to stream music. It gets loud enough that you can't have a conversation anywhere near it at full volume, and a "comfortable" listening volume is probably somewhere around the half way point. The audio AV jacks work similar to the stereo red to red white to white then you just have your positive negative in ground.

The bluetooth input, coupled with the 4 RCA inputs allows you to connect a microphone and a guitar plug easily, for traveling amplification. It is waterproof with its marine grade rating of ip. The sound quality is also very tinny and hollow sounding.

It fits easily under the passenger seat and packs enough power for.

This amp is pushing 6 @ 6-1/2" and 1 @ 12" Sub and sounds great. It is only stable down to 2 ohm in stereo on the 4-channel side and it is stable to 2 ohm on the sub side. It does run hot though and also it is father's day gift.

Best value For money: Boss Audio systems Small Marine Amplifier

Buy on Amazon

The look and feel of this amplifiers are consistent with the decent quality we're used to from the rest of Boss Audio Systems's lineup. The amplifier is a great option if you have speakers that are 2ohm, or are planning to utilize dual voicecoil drivers, but in order to get that 400 watts you are looking for, you will have to understand how to get it. It is bridgable, therefore can be used to power two subs. If you use 4ohm speakers, it will only deliver a maximum of 50w to each speaker, which is not much more power than an aftermarket stereo head unit provides.

The amp is rated at 400w Maximum Power. It has a positive and negative terminal. It provides all the wires necessary to hook the amp up. It has a single 15a fuse to protect it. This product will work great with your factory door speakers. It has no frequency controls so it will play treble through the subwoofer besides that this Camp is able to clearly push a 10 inch sub just not designed for that application.

• Has good amplification to the system
• Sounds amazing with the marine system
• Good investment for long term
