Well, I don't have any pics of the connections yet, but I'll get some tomorrow hopefully. I ran the power wire (10 ga.) from the battery, through the firewall, up the A-pillar, and along the top of the doors underneath the weatherstripping, then down to the basslink. The ground (also 10 ga.), I took out one of the bolts holding the back seat down, hooked the ground to that bolt and then fastened the bolt back down.
As for the signal, you can use the speaker level inputs that come with it if you have your factory radio still, but I used RCA connections from the back of the HU, and underneath the doors to the basslink. You also have to run a remote wire from the HU to the basslink. So basically, if you get a typical amp kit (got mine from wal-mart for $17) it should have everything you need in it already.
I don't take credit for any of my ideas for running the wires, I had alot of help from searching this forum. I actually messed it up when I tried to run the power wire through the firewall. I didn't know about the hole that was already there and I tried to push it up through the main gasket in the firewall...that didn't work! It pushed that gasket completely out and I couldn't get it back in so I had to go and pay someone to fix it. Oops!
