Alpine PDX-5M 5-Ch Digital Marine Amplifier
Still overheats
I have this installed on my pontoon boat and it pushes 4, 6" Memphis speakers and a 12" sub at 400 watts. It is powered by an independent bank of AGM batteries using large cabling (less resistance), yet this amp still overheats in warm weather. I had to install a fan in the amp compartment to dissipate some of the heat so we could keep the tunes going.
