PowerBass is pleased to introduce our newest series of Class A/B full range and Class D bass amplifiers. Borrowing from our classic ASA series, these new amplifiers offer the most desired features in the most compact chassis allowable. To accomplish this we selected SMD parts and engineered a brand new 6 oz/kg high density heat sink engineered for maximum efficiency and cooling.

The result a line-up of two, four and mono channel models that offer great performance and fantastic value. Ultra efficient, the ACS amplifiers produce plenty of low distortion high fidelity audio in a footprint small enough to fit nicely in nearly any vehicle. If you are seeking the perfect mix of performance and value look no further.
