Good bang for buck!

Replaced a 4 channel marine amp previously in boat and sounded really good

By Danny on March 30, 2018

Kicker 300.4 - GREAT AMP

I have 3 of these amps in my boat and love them. 2 of them are bridged to power 4 kicker tower speakers which are very loud, very clear, and very energy efficient. The 3rd is used to power 4 deck speakers in my boat for when the tower speakers aren't being used. Be sure to keep them ventilated or they will get hot and shut down if they're in an enclosed space. If you've got them cranked, they will get hot, almost too hot to touch, but as long as the amp locker or cubby has open air flow, they're fine. This amp also comes with a "birth certificate" of certified power, and all 3 amps I've gotten have been in the 340-350 RMS range so it's like getting some extra watts for free :)
