ROCKFORD FOSGATE
ROCKFORD FOSGATE Punch Marine Mono Amplifier
The PM300X1 is a 300 Watt mono amplifier with high dynamic power using Class-a/b technology and a conformal coated pc board designed for motorsport and marine applications.
The PM300X1 is perfect for use as a dedicated subwoofer or center channel amplifier. Regardless if you're driving multiple speakers or just one, the hefty 2-ohm capability will deliver the right amount of PUNCH that you want! Now, thanks to its small chassis design, it will also fit where traditional amplifiers cannot.
