Rockford Fosgate showed at CES a mini amp that can sit behind car speakers in the door or just about anywhere to deliver power without the need for connecting the amp to the car’s battery.
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 B+/GND to it, all while presenting a safe load to the OEM radio. It uses patent-pending FreeLoad technology that takes in a speaker-level audio signal for amplification and then stores unused voltage from the audio signal to deliver up to 100 watts RMS power at 2 ohms.
- Patent Pending BTL Powered “Harvester” Technology
- Harvests both B+ and Audio Signal From Standard HeadUnit Speaker Outputs
