DSP Data Interface with Pre-wired Harness - Fits Select GM Models 2006-2020

Overcome the factory radio’s built-in “audio processing” with our patented digital signal processor, or “DSP”, vehicle-specific packages. Factory radios have built-in sound processing designed to make your mass-produced factory speakers sound as good as they can without breaking. This means that if you upgrade to aftermarket speakers, your factory radio will process the sound according to the factory settings and your system just won’t sound as great as you hoped it would. To remove the limitations of the factory radio and get clean signals for aftermarket audio gear, you will need a sound processor like our line of patented DSP products. Our DSP is unlike any other on the market offering not only serious sound improvements but retains many of the features commonly lost when upgrading a sound system.
