He hasn't even logged in for over 2+ years so I doubt he will see your post. I wouldn't mind seeing your build if you decide to take and share some pictures on here though.
Not that this will be any help, but I did multiple builds in a 2007 Tahoe. Not that any of it was great but if you want to sift through the old threads for ideas I will share a couple links below. Thanks.
I have a 14' Silverado with Bose stereo so did you do integration or add a Head Unit some where? What did you do to have it completely separate? Thanks.
PM if need be, not trying to thread hijack.
