updated Pics with new wheels and audio install 08 LTZ

Thanks guys for the comments. its been a lot of painstaking work to get what u see done as I have done 99.5 % of it myself.

srobinso11 - I cut a hole in the side of the battery cover with a hole saw directly inline with the + terminal for the stereo wire. I also cut the factory steel battery connection ring off and I bought a streetwires battery terminal with multiple connection points so I could connect my stereo power wire and my stock battery wire which i crimped a new connection ring on the factory wire and just connected both cables to the new battery terminal. I still have stock battery but upgrading soon to an Optima yellow top. no second battery but do have a 4 farad cap in trunk that is hidden. The LTZ has a stock 156 Amp alternator so with the wattage I am running it is sufficient for the current draw. I can take pics of battery if u want.

flrdotcom - no I did not dynomat anything. I did have serious rattle with the sunroof motor and bracketry under headliner but i bought a piece of foam mattress pad and cut small pieces and put it under headliner to take all vibation and rattle from inside the car. no rattles whatsoever. outside has no rattles whatsoever. not even licens plate. this has a lot to do with my subs are sealed off from the trunk pointing into the cab of the car. the trick is to seal the cab from the trunk. with my seats down.

Randy_S - Yes those are the Art seris from the Mid 90's very hard to come by in good condition and sound quality is top notch. Im all old school as far as amps go.

I am underpowering the W7's by atleast 400 watts per sub and if I had to guess I am hitting about 140 145 db. plenty enoug boom for the daily driver
