Rockford Fosgate PM500X1bd Monoblock Punch Marine Amplifier

Rockford Rockford Fosgate PM500X1bd Monoblock Punch Marine Amplifier

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.

Rockford Fosgate PM500X1bd Monoblock Punch Marine Amplifier

Rockford Fosgate's Moto-marine amplifiers have not only the capabilities you expect a Rockford Fosgate amp to have, but they have designed them to stand up to the environmental conditions you are likely to subject them to. With corrosion resistant stainless steel hardware and two-part epoxy coated circuit boards, these units are designed with you in mind. Whether on the lake, on the road or in the back woods these amplifiers are ready for an adventure.


  • Dust - Rockford makes sure that displays and motor structures are sealed up tight so they look as clear as possible and perform day in and day out no matter how many times you hit the trails.

  • UV Inhibitor Materials - Centrex and ASA plastic materials are used for their UV radiation resistance and components are tested in accordance with ASTM D4329 testing and certification procedures.

  • Corrosion Protection (Electronics) – Two part epoxy coated PCB boards prevent corrosion of critical components due to exposure in moisture rich environments.

  • Stainless Hardware – Stainless hardware is used due to its natural resistance to corrosion and rusting. This ensures that electrical connections will not degrade over time due to exposure to the elements.
