PM100X1K

The Rockford Fosgate PM100X1K is a compact amplifier set featuring two powerful single-channel amplifiers designed specifically for easily upgrading existing audio systems. Thanks to patented FreeLoad technology, the amplifiers utilize both the audio signal and the available electrical power from the existing speaker outputs. With compatible radios, this allows for operation without a separate power supply line.

Each amplifier delivers up to 100 watts RMS into 2 ohms, providing a significant increase in power compared to conventional radio outputs. Their exceptionally compact dimensions make it easy to install them discreetly right next to the speakers.

Thanks to its protective-coated circuit board and IPX6-rated water-resistant design, the PM100X1K set is suitable for use in vehicles as well as in marine and motorsports applications.
