Overview
The DSR1 combines a full-featured 3Sixty digital signal processor with an integrated, flashable iDatalink Maestro module. It accepts high- or low-level inputs immediately, or can be flashed with vehicle-specific firmware to preserve factory controls and features. Tuning and sound-profile adjustments are done through Rockford Fosgate’s PerfectTune app.
Best for
- Integrating aftermarket processing while retaining factory source unit controls
- Replacing factory amplifier and speakers in compatible Ford and Chrysler vehicles
- Installers and enthusiasts who want app-based tuning via Apple or Android devices
- Systems that require both high- and low-level input compatibility
Key points
- 8-channel interactive digital signal processor based on Rockford Fosgate 3Sixty platform
- Integrated, flashable iDatalink Maestro module for vehicle-specific firmware and integration
- Out-of-the-box operation with high- or low-level inputs
- Allows retention of factory controls and features after flashing vehicle firmware
- Tuning and adjustments via Rockford Fosgate PerfectTune app (iOS and Android)
- Uses the full-range, flat audio signal from factory source units for certain Ford and Chrysler integrations
Fit and use
The DSR1 is designed to be added between the factory source unit and the rest of the audio system. It can be used immediately with high- or low-level inputs, or flashed with vehicle-specific Maestro firmware to enable CANbus-based control and internal signal routing. Final sound tuning is performed with the PerfectTune app; software and updater utilities are available from the manufacturer.
What to know
Flashing the Maestro module with the correct vehicle-specific firmware enables preservation of factory controls and full integration; without the flash, the unit still accepts high- and low-level inputs. Use the PerfectTune app and the manufacturer's updater utility for tuning and firmware updates. Consult the product…

Additional details
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.
