Bose Amplifier working in Infiniti G35 w/Pioneer Z110BT and Metra 70-7551

I do not recommend purchasing this harness any more, use the PAC ROEM-NIS2 adapter (http://amzn.to/ZoUCoK) instead of the 70-7551. There are MANY (including professional shops) who report terrible sound quality and volume using the same method and parts install I used here. I only leave this video because some shops give this wiring harness free with a radio, so it's worth a shot before buying the ROEM-NIS2. If this way does not work for you, you need the PAC ROEM-NIS2 adapter (http://amzn.to/ZoUCoK) instead of the 70-7551. To do it the way I've done it, you connect the amp ground wire from the 70-7551, the ground wire from the 70-7551, and the ground wire from the factory harness together. Ground this to the body of the vehicle.
