The PM100X1 is a 100 Watt dynamic power mono amplifier that uses DC and AC voltages present on existing speaker outputs of a radio. This design allows connection to a speaker wire without directly connecting power cable to it. It also presents a safe load to the radio amplification circuit so you do not have to worry about excessive wear and tear on the radio, making it ideal for interfacing with OEM and aftermarket radios alike.

It features a 2/4-Ohm input switch to configure it to the output load capability of the radio, as well as a selectable high pass crossover with settings at 60 Hz, 80 Hz, and 100 Hz. The unit is also IPX6 rated for those applications where moisture may be present.
