Package Includes:

• (1) Rockford Fosgate PM500X1BD 500W RMS Monoblock Marine/Boat Amplifier Punch Amp
• (1) Rockville RMWK4 4 AWG Gauge Waterproof Marine Amplifier/Amp Install Wire Kit

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.
