looking for a good ground point 07' in tahoe
 

i'm looking for a good ground location within close proximity to the center console. i replaced all the speakers with alpines and installed an alpine pdx 4.100 but can't really enjoy it. i have to keep the gain turned almost completely down until i can find a better ground because the noise is unbearable otherwise. any suggestions are appreciated.

Kick panel is the best spot for a ground location but anywhere into the body will do. Do not use a part that is bolted to another part.....go straight into a body panel. Scratch the paint off to expose bare metal, and use a self tapping screw to attach the wire. Don't overtighten it or you will just strip the screw hole
