PB-90.4 90W RMS X 4 CLASS A/B FULL RANGE COMPACT AMPLIFIER

PowerBass is pleased to introduce our newest series of amplifiers, the PB Series! The PB-90.4 is a CLASS A/B FULL RANGE Amplifier in the PB Series providing unrivaled sound quality and driver control.

Borrowing from our 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 we 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.
