I'm trying to install an aftermarket amp on my aftermarket system. I cannot find a good pathway to use near the passenger side firewall. Does anyone have any suggestions?

No advice, but good luck! And nice Expo what color?

It's a dark blue. I'm not sure of the exact name, but it reminded me of the color of the New York "Football" Giants helmets. Since I saw it, I fell in love :) !

Wedgewood Blue I think, same as mine.

you have to pull the power cable from the passeger side through the back and over to the drivers side there you will find a opening that is big enough for you to use
