I found a much much better solution to two huge problems I was having with the screen.
1. Holding the circuit board to the back of the screen.
2. Holding the bezel into the dash.
Solution: sticky velcro. It has a sticky tape backing on one end so you just stick it to both sides and velcro them together. I was talking it over with my friend and he just suggested it to me like I was an idiot.
Here are some updates since I made this topic.
Here is a picture of the 4 gauge wire for the subwoofer amplifier going through the firewall.
Here's the awesome Street Wires cable I got for the speaker wire. It's 8 wires (2 per speaker) and a remote lead all neatly wrapped in a nice thick jacket. 20 feet of it for $30.
And here's the heat shrinked and soldered joins to the wiring harness. I just plug the harness into the dash, plug the wires into the amp and I'm done.
I've also got an air ride suspension coming which has its own screen I will put on the visor, and I'm looking at a unit called Connect2Car as well.
Would you mind taking a few more pics of how you mounted the computer/amp? (I see you made an enclosure in the trunk). I am trying to do the same. Keep up the good work.
I'm moving the location of everything in the trunk, I'll take pictures of the new places once it's done. Just too hard to do when it's -20 outside.
I've relocated the amps and computer, I'll get pictures for you once my car comes back from paint. Here's an updated picture of the exterior.
