CTAMPPASSTHROUGH – Amplifier Retention Adapter for OEM Amp Integration

The CTAMPPASSTHROUGH is a smart amplifier retention interface designed to convert a new aftermarket head unit’s high-level speaker output into a low-level signal compatible with the vehicle’s original factory amplifier. This ensures correct signal levels and prevents overdriving the OEM amp, preserving both sound quality and amplifier functionality.

It connects via a single 8-way ISO plug, allowing it to sit seamlessly between the head unit and the vehicle-specific stalk harness. For optimal functionality, it should be used alongside a stalk harness that includes an amplifier remote output wire.

Perfectly suited for vehicles like Mazda Bose and Saab Bose systems, the CTAMPPASSTHROUGH allows integration with OEM low-level pre-amplifier inputs from the original radio, making it the ideal solution for maintaining the factory amplifier setup when installing a new stereo system.

Professional installation recommended for best results and system safety.
