well it's not much but here's an update. I've put in a jensen cd player, my kicker l5 12" and I'm still putting in my dhd power crusher amp. I've got to finish figuring out how to mount the amp. so far I've come up with mounting it to the side of the box so it can get some air flow. It's got two cooling fans in it. Last wire to run is the turn on wire. Then plug the amp in. I do still have to do the ground for it. I did some work to the battery wires so they work better. I found out when I pulled the carpet back to hide the wires that there was no rust under what I pulled back. It looked like it was a brand new floor clean and shinny. It was well kept by someone. I couldn't be more pleased with this one. I wanted to hide the amp but want it to get some air still. Still looking for info on the tbi unit. It's driving me nuts.
