Features

Overview: In the 1997-2004 Chevy Corvettes there are not 12-volt accessory wires currently in the factory harness making the installer run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The Metra Axxess XSVI-2004 Amp Interface is designed to provide a 12-volt, 10-amp switched accessory output along with the rest of the wires needed to install an aftermarket radio.

R.A.P.: The R.A.P. (Retained Accessory Power) function, where power is supplied to the radio after the ignition is shut off until one the doors are opened is retained by the XSVI-2004 Amp Interface module.

Differential Line Converter: The XSVI-2004 will also retain the amplified door woofers through the use of a differential line converter. This helps eliminate turn on/off pops and allows you to adjust the level of the doors woofers. The XSVI-2004 Amp Interface module features four potentiometers (Front left/right and Rear left/right) to increase or decrease the audio level of the door woofers.

Installation: The Metra Axxess XSVI-2004 installs behind the vehicle's factory radio and connects between the factory radio's plug and vehicle harness. The XSVI-2004 Amp Interface module provides plug-in connectors as well as hard-wire connections.

Initialization: Once all the connection are completed, turn the vehicle's ignition key to the "On" position for thirty seconds and then turn the key off.

Perfect for wiring into Bose factory and other factory systems without cutting things up or out of the system. Bose makes great equipment. Why would you want to cut it out or bypass it when this will work it into your system flawlessly.
