Kubota RTV Punch Marine 500 Watt Class-BD Mono Amplifier by Rockford

The PM500X1bd is a 500 Watt mono amplifier with high dynamic power using Class-bd technology and a conformal coated pc board designed for motorsport and marine applications.

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