American Bass MR 160.4

HIGH-POWERED, AMPS DESIGNED SPECIFICALLY FOR MARINE ENVIRONMENTS AND BATTERY POWER. FULL-RANGE SWITCHING TECHNOLOGY AND LOW POWER DRAW TO CONSERVE DC POWER. A heavy-duty, 2500-watt, subwoofer amplifier engineered to deliver solid, deck-rumbling bass uncommon in most marine systems. A great add-on to the MR 160.4 robust four-channel, full-range amp. Like all American Bass Marine products, this amp is designed to withstand years of exposure to harsh environments and late-night parties.
