Rockford Fosgate Marine PM400x2 - 2-Kanal Verstärker

The PM400X2 is a 400 watt 2-channel amplifier with high dynamic performance using Class A / B technology and a conformally coated printed circuit board for motorsport and marine applications.

Whether you want to drive high frequency component speakers or low frequency subwoofers, the PM400X2 has the power and flexibility you need to add a serious PUNCH to your vehicle. The performance of such a small amplifier is a great match for a 2 ohm DVC subwoofer or a pair of 8 ohm SVC subwoofers.
