Rockford Fosgate All-In-One Digital Sound Processor & Amplifier Replacement DSR1

This listing includes:

  • (1) DSR1 Digital Sound Processor

  • (1) 7" microUSB-to-USB cable

  • (1) 18-pin input harness

  • (1) 16-pin output harness

  • (1) Quick-Start Guide

Co-developed with iDatalink Maestro, the DSR1 combines a full-featured 3Sixty digital signal processor with a flashable Maestro integration module. The DSR1 can be used out-of-the-box with high or low level input, or with a quick flash download to add vehicle specific firmware to enable integration without the loss of factory equipped controls and features. Once connected, complete control of the sound profile can be adjusted using the proprietary Rockford Fosgate PerfectTune software.

Download PerfectTune on the App Store or Google Play to control the DSR1.

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.
