Default Wiring issue on V1

For anyone who read my previous thread, my V1 was totaled a while back. Long story short: it's been rebuilt. When I got the car back the radio worked but there is no sound from the speakers. Everything worked before the shop rebuilt my car so I'm assuming something just isn't hooked up properly.

The right side quarter panel was replaced, door and trunk removed, rear windshield removed, amp removed, etc. so I'm positive that my issue. I checked the amp and the connectors on it are secure. I checked all fuses labeled radio, amp, speaker, etc. and they are all good. So aside from the connectors on the amp and the back of the radio, where should I look?

My rear defroster no longer works either. It turns on but the back window doesn't hear up. My guess, again, is something is unplugged or not grounded. Does anyone know where to look for that?

If anyone has any insight that will save me some time hunting down the issue that would be amazing. Thanks!

Anyone in here with access to wiring diagrams to a 05 or perhaps someone who has taken a look at audio wiring by chance?

For some reason they won't display. Probably because I am using an iPod lol. I'll check when I get home from work, thanks man

Edit: in short, where is the amp grounded on the car? If anyone knows that I can check at work real quick. If not ill just take a peak at those diagrams tonight

I believe there's a ground on the passenger side of trunk. That's been known to cause some issues with all kinds of strange things.

It's been crazy cold up here lately so I haven't worked on the car yet. Thanks for the starting points, I'm sure that will help a ton
