I have a '94 Mustang coupe. I'm about to try to install a subwoofer and
power amp in the back and of course I have to run a couple of wires for
power, etc.  from under the hood to the trunk. On past cars I've run them
through the firewall with no problems but on this car I can't find a spot
where the wires won't rub, etc. Any one have any experience and/or
suggestions on running wires through the firewall. I'm trying to make this
as painless as possible without taking the car apart too much. Any ideas for
spots to try would be greatly appreciated.

Thanks!
