thanks alot guys. didnt bypass the voltage regulator, so no need for it. My voltage barely drops below 14.4

Yes amps are grounded to the frame, but keep in mind both batts are grounded together, and both are grounded in two spots to the frame, plus two grounds from the engine to the frame.

Nice build! Wiring is really clean. But, your doors/mids could use some work. Get those tweeters up to the A-pillars, and seal off the door. You'll notice much better sound in the front stage as a whole.

Actually, the doors are completely sealed, i just forgot to take a picture of them when i was finished. there are no holes in the door skin now.

There are tweeters in the a pillars as well as in the doors (DRT25 Titanium in doors and CDT Upstage kit tweets in the a-pillars). images really well. i am very happy with the frontstage, the upstage tweeters really raise the image well.

much better than in my monte carlo.

Hmm, my friends voltage goes from 11-14v, maybe his dash is metering wrong. We wanna run 2k plus in it but were worried about the alt. (2010 Silverado)
