I just put an Alpine CDA-9886 HU in my girlfriends 2000 TTQR. Everything works perfectly except when I turn the car on or off or change source it makes a really loud popping noise. Just a heads up I used the metra 70-1787 wiring harness
Get at oem-2 or the equivalent to "dumb down the signal" a bit and it will get rid of the pops.

I found a post on another site that said to put a ground loop isolator in and that would work too. My only other question if that works is what do i do with the brown wire that was originally attached to the back of the factory deck?
Brown wire is an extra ground.
Ground loop isolator shouldn't fix your problem.
