Hello! I two 12" subs in the trunk of my Cadillac. I have ran the RCA, Power Control, and Power wires through the trunk. RCAs and Power Control are both connected to my head unit. I just cannot seem to find a hole in the firewall to fit a 4 gauge power wire through. I can't find any holes at all, as a matter of fact.

If there are none, I will be willing to drill, but only in a safe location.

Pictures will help! Thanks!!!

Under your hood back on the fire wall under the master cylinder and brake booster you should see a black plastic coded cable in the middle of something that looks like a rubber stopper pull that stopper out and that should give you more then enuff room for your cable
