2004 HSE Stereo Issues - HELP!!

[04hserr]

Hello everyone I'm new to the site and it looks like you have some great info here for our vehicles. I just recently purchased an 04 HSE from a local dealer where the truck was a trade in. The story I got from the dealer was that the previous owner had removed his satalite radio setup from the truck before it was traded in and now the radio/Nav is not putting out any sound through the speakers. I am pretty mechanically inclined and decided to bargain with the dealer on price with the stipulation that I tackle the wiring for the radio/amps. After taking the vehicle from the dealer I got it home and opened up the left rear quarter panel to find a harness laying there. I assume it was to add a feature to the truck. Everything else looked intact except for a few plugs I found. I have a few pictures and was wondering if anyone can help me out. Just want to know if everything looks wired properly. I am leaning towards a blown amplifier right now (the one closest to the taillamp). I bought a used front amp from I salvage yard I deal with and had no luck. In the pictures I have already removed the rear amp and should have the new one tomorrow. Just give me a heads up if any of the larger plugs should be going to another module or connector. Thanks alot Mark

Also if anyone would mind snapping a shot of their inner left quarter panel that would me great

I will assist if I can

Firstly I find it amazing that so many viewers can look at this and not at least offer moral support.
In my view that is what Forums are about and I hope that comment does not offend anyone.
My car does not have the GPS system so it may be different to yours.
I have a 2003 HSE TD6.
Tomorrow I will take photos of the area that you ask for but first tell me what you are looking for if you can.
Why tommorow you may ask? Right now we are having the wettest May day in 17 years and it is dark and cold out there.
I have a full set of workhop manuals and if you need scanned pages just ask.
You are somewhat courageous taking this on but then that is how we all learn.
Feel welcome to send a private message if you wish.
