NOTE: If you have the Bose sound system, we the technique for installing your amplifier will slightly be different as you will need to bypass the factory Bose amp if installing a 5 channel amplifier. Instead of using the Axxess T-harness, you will use the harness linked below which you will bypass and create a T-harness at the Bose amplifier, leaving the factory radio alone. It will be the same technique, just completed at the Bose amp located under the passenger front seat. If just simply installing a mono amp and sub, no bypass is needed, and you can access the Bose subwoofer for signal in the spare tire compartment.
