Rockford Fosgate Marine PM500x1BD - Mono-Block digital

PM500X1bd - Punch Marine 500 watt class-bd mono amplifier

The PM500X1bd is a 500 watt mono amplifier with high dynamic performance using class bd technology and a conformally coated circuit board for motorsport and marine applications.

With its super efficient Class BD circuit topology, the PM500X1bd drops some serious BASS! Due to its special low frequency response, this amplifier is only optimized for mid-bass speakers or subwoofers. No need to worry, as the 1 ohm capability will drive a pair of 4 ohm DVC subwoofers or the quad configuration of 2 ohm DVC subwoofers with ease.
