Nice setup! I just finished building a sealed box, false wall and running the electronics in my car. I also bought Technic's harness/LC2i kit for plug n' play. Everything I put in is quick disconnect and comes out quick for track days. The only area I am having trouble with is visually locating the remote wire behind the seat bolster. I found the coax and several black wires but they all seem to have stripes on them. The volt meter comes out today to wrap this up.
I bet those W3's sound great. I went with 2x 10w6v3's and HD750/1. Ready to be a basshead once again.
