hey guys whats up, i got a 2000 gp for my first car, im wanting to put in a system and i was wondering if there is a hole in the firewall to connect the ground wire to the battery, or the fuse box...i found a hole but im not sure where it leads to
thanks for the help!

 

I had to drill a hole in the firewall. There is a groumet in the firewall for the shifter cable, however the hole isn't big enough for an audio power cable and the shifter cable.
