Hey guys. I just picked up two Alpine 10" Type R subs and a 1000watt Rockford amp. I've already blown enough cash on the equipment and don't really feel like spending the extra 60 bucks to install it, so I'm going to try to do it myself. I've got an '88 GT convertible. I was looking for a hole in the firewall to run my 4gauge wire through to the battery, but didn't really see one. Do I need to make a new one? Also, what info could you supply to help me with the installation? Do I need to run the speaker wire to the deck on a separate side from the 4gauge? I'm going to be putting the subs in my trunk in a dual enclosure. Any advice?
