So i decided to hook up my aftermarket stereo and i got the harnesses from metra. I have it all hooked up except the powered 6x8s in the back deck. I have no idea what to do with the two light blue with white stripe wires. Or the amp ground wires. Please if one of you fella can help that would be awesome. Ive already read the tech articles and searched here and google and im coming up empty handed thanks its greatly appreciated
