Not sure how to run Amp power cable (4 gauge) from Battery to Trunk (1993 Deville)

1993 Cadillac Deville

Well, a friend and I started the amp + subs installation today. We got the RCA cables ran to the trunk without any drilling or cutting at all, just removed the bottom back seat and found an already existent factory space to run them through. I couldn't get the top part of the back seat off though, no matter how many times I tried and from many different angles of pressure. I just gave up and found a way to run it wtihout removing that part of the seat.

Anyway, we can't seem to find a spot to run the 4 gauge power cable through to get it inside the car and to the trunk. Anyone with experience installing amps and wiring stuff in a 1991-1993 Deville, lemme know where I can run this wire through at please!

We're gonna (hopefully) finish the install tonight if we can find somewhere to run the cable through.

I'd prefer somewhere on the passenger side, as thats where the battery is at, and the cable might not be long enough if ran through on the driver side.

thanks for any help

Well, I don't know much about Caddy's but my Silverado (a GM product at least like the Caddy) had several "punch outs" in the floor along the door sills. I actually used one on the passenger side and came up through the floor with (2) 4 gauge amp cables. Worked like a champ and I simply used a rubber grommet in the hole and siliconed the crap out of it once everything was done. It's close to the door sill so once the carpet padding and carpet was set back over it you cannot even tell those cables are there. Helluva a lot easier than try to go through the firewall.
