Description

The Ads/Maestro HRN-DSP-GM3 is a T-harness designed to add a Rockford Fosgate DSR1 processor to select 2014-up Chevy and GMC vehicles without a factory amp. It allows for the integration of digital signal processing and aftermarket amplifiers while retaining important GM features and functions. This harness connects to the factory radio's harness, supplying necessary audio and databus signals to the DSR1's Maestro interface without requiring any wire splicing.
