Awesome truck. I'm loving the audio system! Are you running the stock alternator or do you have a Hi-Amp Alt. I had a similar set-up in my camaro (minus 1 w7, 1000/1 and 300/2) and even with a Hi-Amp Alt, secondary battery, and capacitor I still had dimming issues. Like others have mentioned if you fix the few problems it will probably sell faster but props for pointing out the issues ahead of time for potential buyers. You're a stand up guy for doing that, as most people will try and pull a fast one on others, especially on ebay.
