Stereo: Running Power?

[sykikchimp]

I'm going to be running a 4 gauge power cable to the hatch of my 92' to push my future system (it's all in the fedex/ups shipping system comming too me.)  

Any suggestions on where to run the wire?  I noticed there isn't really anywhere to run a power cable (especially 4gauge) through the firewall.  I was thinking about running it under the car, but I wouldn't know where to bring it back up?  (might be a stupid idea too)

Actually, I fitted a 4ga wire in the firewall.. It was a real PITA though....  check these pics  You don't really see well where it's passed but its the steering column area... very hard fit, trust me!
