Audi A2 A3 A4 TT 2008 On Car Stereo BOSE System Rear Amplified Active Speaker Quadlock Interface Adaptor

Only for use with BOSE half-amplified (rear speakers) audio systems

Converts the Audi Wiring Harness to Speaker Level Inputs for connecting to a new car stereo with ISO Lead.

Most Audi's have active rear speakers built into the speaker themselves. These adaptors convert the new head unit you are fitting to activate the speakers.

This adaptor is required to replace factory fitted radio with an aftermarket headunit (Alpine, Pioneer, Kenwood, Sony, JVC etc.). It will convert the car original power and speakers wiring connector to a standard ISO connector. Simply plug one end of the adaptor into your cars wiring harness, and the other end into your new radio, without the need of tools or cutting of wires.
