Rockford Fosgate DSR1 Digital Signal Processor

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.
