Rockford Fosgate DSR1 processor

Sale price $479.00 Regular price $749.00

Tax included.

The DSR1 is the first real solution for replacing the factory amplifier and speakers in Ford and Chrysler vehicles, as the DSR1 uses the full-range, flat audio signal from the factory source unit.

After the built-in Maestro interface is flashed with the vehicle-specific firmware, the factory source unit CANbus messages are used to control the internal signal routing of the DSR1. The DSR1 still utilizes the power processor found in our patented 3Sixty.3, but adds an easy to use app for tuning from Apple and Android devices.
