I have a 2008 G37 S coupe and I need to replace the factory audio. I have all replacement door speakers including tweeters, 2 JL Audio 10" woofers, 2 rockford fosgate punch amps (1) 300w mono for the subs another 300w 4 ch for everything else. I also had to purchase a sound processor (audio control LC6). My issue is finding the stock amp(s) so I can tap in. I believe it is built in the deck? If anyone can please help me by giving some insight as far as a schematic wiring diagram or even color code for audio wires I would greatly appreciate it.
