I took a look at my Bonnie a few mins ago to see how I can possibly route my amp feed cable, but couldn't find a good point of entry for it...not even a good spot to drill into the firewall. So I thought about running it underneath the car...is this the best way or is there another way?

no do not run it under the car. there is a point in the firewall behind the driver'* side strut bar where there is a black wire that runs through the wall. you can fit up to 4 guage through there without modification but you will most likely need to run a pull wire through there first. i have a few pics of what im talking about on my cardomain page http://www.cardomain.com/memberpage/300261/3

Are you sure that there is no place to run wires on the passengers side?? I would hate to have to run wires all over just to get in to the trunk.

There is a spot on the passenger side, but it is more of a pain to run it through. take off the black cover and unscrew the little air bag box and run it through there, just be careful. you also might have to take apart your globebox to get it through..

Plurr nailed it right on the head. Using the same hole he did is really easy. First I ran a small, rigid, pull wire (like you'd use to hand ceiling tiles) through the hold to see how I came out on the other side, and I folowed that same hole and enlarged it with a large philips screwdriver (all of this from under the dash on the driver'* side). Then, resinserted the small, rigid wire, made a loop on the end, criped it to the wire to pull through, and pulled it through. It'* a tight fit because there'* so much rubber, but it'* really quite easy.
