amplifier power cable routing

ok I did do a search and couldnt find anything. Im trying to install a infinity basslink and need to run a power cable from the battery to the rear of my 2-door 2005 Jimmy(blazer). where do you guys run your amplifier power cable routing through the firewall. This is my first do it yourself install and im at a standstill before I even started-lol.

there are a few grommets on drivers side where throttle cable, hood release cable, but pass side, between your feet right under top edge of carpet works for most.  antenna grommet.

Thanks I will check it out , im supprised their isnt a sticky on amp install that included routing.

Thanks for the info. I routed under the fender in through the front drivers door. You would think that by now, car manufacturers would have designed another terminal in the rear for systems. Hmmm... do I smell an invention?

That can run extra cabling through the body or ceiling or under the carpeting, and put up a terminal for positive, and make a ground as well.

I bet that would fly in the car market.

I would doubt it...

I would be very careful having it just run through the door opening.
