ROCKFORD FOSGATE
ROCKFORD FOSGATE Punch Marine 400 Watt 2-Channel Amplifier
The PM400X2 is a 400 Watt 2-channel amplifier with high dynamic power using Class-a/b technology and a conformal coated pc board designed for motorsport and marine applications.
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.
