Rockford Fosgate Punch 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. The PM100X1 amplifier uses our patent pending BTL technology to provide you a very unique amplifier solution. This single channel amplifier utilizes the speaker output of the radio to not only provide the audio signal it needs, but also the power that runs the unit. This is done through a combination of the DC offset voltage commonly present and the audio AC signal itself.Initially, it uses the DC offset voltage for its turn on power as well as primary amplification power. As volume is increased and the output power demand r
