I purchased a PA 880 amp for my boat. I have it hooked up to my Panasonic CQ-C1401U deck, sub-out rca cables. I am driving 2 Kicker 12" Comp subwoofers. I have them installed in a sealed box with a full partition between them, with about 1.1 cubic feet of space each....that's all I have room for. With the head unit set at max, and amp powered up I am TOTALLY underwhelmed at the performance. My in dash 6" factory speakers have more kick. Any help is appreciated. My wife will be ticked if the money spent doesn't produce something......
