Punch Marine 100 Watt Full-Range Mono Amplifier (Pair)


The PM100X1 is a 100 Watt dynamic power mono amp using DC and AC voltages present on existing radio speaker outputs. This design allows connection to a speaker wire without running a B+ cable. It also presents a safe load to the radio amp circuit to eliminate excessive wear and tear on the radio, making it ideal for OEM and aftermarket radio integration. The conformal coated PCB allows for mobile, motorsport and marine applications. PM100X1K "KIT" ships with 2 pcs.
