Rockford Fosgate Punch Marine 300 Watt 2-Channel Amplifier (PM300X2)

The PM300X2 is a 300 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.

The PM300X2 is a solid choice if you're looking to drive a pair of coaxial speakers, component speakers, or a single subwoofer. The amplifier can also be run in stereo/mono mode simultaneously when using passive crossovers (not supplied) on all speakers. With proven PUNCH technology, the PM300X2 delivers real Rockford Fosgate power from a small design and is flexible to accommodate any moderately sized system.
