Installing an amp..need help

Mm'k I'm going to install an amp tomorrow..just wondering if there was anybody else who's installed an amp themselves, cause I want to know if there is already a hole in the firewall for the battery wire..or if you just made one..just want to know before I start tearing my dash apart looking for a grommet. thanks in advance

There's a grommet that goes around the steering rack through the firewall. You can use a drill bit to go through the rubber. Make sure not to hit the lines that run underneath of the master cylinder. Then attach the cable to a coat hangar & push it through. Make sure you also run the RCA's separately from the power for no noise problems. Have fun!
