Amplifier retention Mazda MX-5 / 2 / 3 / Saab 9-3

This an amplifier retention adapter which converts the new head unit’s high-level audio output to a low-level audio signal which will work with the vehicle’s original amplifier (reduces the output volume from the aftermarket stereo to the factory amp).

This lead should be used in addition to a stalk harness which features an ‘amp remote output’ when upgrading the vehicles head unit.

The lead features a single 8-way ISO connectors so that it can seamlessly sit in-between the new harness and the head unit’s power connection.

It's ideal when paired with car specific ISO leads for Mazda Bose and Saab Bose vehicles which feature OEM low-level pre-amplifier signals from the original radio.
