Rockford Fosgate PM400X2 2-Channel Punch Series Marine Amplifier

Whether you're looking to drive high frequency component speakers or low frequency subwoofers, the PM400X2 has the power and flexibility you need to put some serious PUNCH in your vehicle. The power available from such a small amp means it's a great match for a 2-ohm DVC subwoofer or pair of 8-ohm SVC subwoofers.

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.
