Product Overview
An owner may want stronger bass or a full-range aftermarket amplifier without replacing the original dash radio or losing factory controls. An add-an-amp interface converts the appropriate factory speaker or data-controlled signal into connections an amplifier can use.
GM used standard, Bose-amplified, navigation, chime, OnStar, and data-bus audio systems that are not wired the same. Vehicle name alone does not confirm compatibility. Compare the radio and amplifier connectors, RPO codes, pin count, output channels, remote lead behavior, and whether the interface is for a factory-amplified system.

- Provides RCA-style output and remote-turn-on functions as shown
- Avoids cutting the dash opening for a new head unit
- Made for matching GM radio and harness configurations
Common Uses
- Adding a subwoofer amplifier to a factory radio
- Keeping factory steering-wheel controls and dash appearance
- Obtaining line-level output from a compatible GM audio system
