Here is my post from Trackitara.com - Throught I would repost here also...

So I have the install done to this point... I say to this point because the long run will be a Carputer. I have a possible computer but not the screen...so I have just put in my MP3 player for now.
I am using a 600w Sony Explode amp to put the sound to my stock (for now) speakers.
1. Removed the carpet
2. Here is the board I painted and glued into the cargo area
3. I installed 1 4 gauge wire, 4 paired 16 gauge speaker wire and 1 rem 18 gauge wire to turn on the amp (speaker and rem wire not shown). It was a very tight fit really. I had to run the 4 gauge wire above the seat belt mechanism to make it fit right. I checked a few days after the wire was ran and it sis not rubbing but I will check again in about 2 weeks to be sure\(so i will post a picture of that later) If it is I will do something about it. The speaker wires are taped every 8 inch or so to keep them together while i was installing and so they don't shift as much.
4. Here is the amp. Here you can see the speaker wires and the REM wire which is wired to the 12 ignition on the wire harness for the radio hook up. This way it turns on when I turn the car on. The only draw back is that I think I should have moved the amp over about 2-3 inches to the right. What do you all think about putting rubber under the amp to help with any possible vibrations? It’s straight on wood. I have heard of people that the base of their amps vibrated and sorted out on the boards inside. Now I have had 2 amps in cars befor but mine had plastic bases not metal like this one. What do you think?
5. Here is the radio area. I left enough extra so I can easily pull them out if I need to fix something. The wires are soldered...how well...I am not sure but it’s hooked up. I plan on going back and putting connectors on the amp side of things and redo the connections on the other end also.
What do you all think? Not the cleanest right now. I want to get the shelf in over my amp hat will cover the whole thing from left to right and have a lip to hold stuff in that might roll around.
Feedback please...
