MB Quart - Discus 5 Channel Marine Amplifier with Top Mounted Controls, 500 Watts - Black

Borrowing from Powerbass's former ACS series, these new amplifiers offer upgraded features, terminals and a dual layer PCB all packed in the most compact chassis allowable. To accomplish this they selected SMD parts and engineered a brand new high density heat sink engineered for maximum efficiency and cooling. The result, an all new line-up of two, four, five and mono channel models that offer amazing performance and fantastic value. Ultra efficient, the PB Series amplifiers produce plenty of low distortion high fidelity audio in a footprint small enough to fit nicely in nearly any vehicle. The PB Series Amplifiers provide the perfect mix of performance and style in a sleek new compact chassis.
