I'm going to install an amp this weekend and thought I'd ask ahead of time:

Is there a good spot to run the power cable from the battery, through the firewall? From past experience it always seems to be a pain to find a good, easy location to feed it through.

I took a glance under the hood tonight quick, but did not see anything obvious, so thought I'd ask.

Thanks.

On my 2004 there is a 1/2 inch hole with a black rubber plug located behind the brake booster that can be seen from under the hood with a flashlight. It can be accessed from under the driver's side dash.

If you are using 0 gauge, I think you may need to drill.

There's an easier place... and it's on the same side as the battery. It's just below the entrance for the heater hoses.

my amps and cap are along the rear wall of my cc, so i ran the power wire outside along the passenger frame rail and drilled a hole to get it inside. it was easier, less potential of induced noise and it leaves room inside for other wires.

I used the same location Blackbeauty did...I used a wire hanger to feed the wire through...If you poke the hanger through from under the hood you will be able to feel it inside. I then crimped the hanger to the cable inside the truck tightly with a pliers and pulled it right on through.

LOL, I could've used both of these examples two months ago... I had to do the research myself, and found both of these spots... I have to say, that is one heck of a sealed up firewall on our Titans... If I hadn't found them, I was going to drill and rubber plug on the doorsill...

I just ran out to the garage to run the power cable through the firewall before the wife gets home and orders me to do something else :)

I ran it from the inside, out, which seemed MUCH easier than vice-versa. So FYI on that.

And thanks again for answering this thread - I am not sure I would have noticed that hole that it was ran through...pretty discreet.

So will a 2guage fit through that same firewall hole?
Maybe, maybe not. You'll just have to try it first to see. Otherwise, just drill a hole right next to it. You just want to be careful so the tight space doesn't put to much of a bind on the cable..The easiest way to get the wire through is get metal coat hanger, and bend it into a straight line...then tape the cable to the hanger very tight, and then from in the cab, push the hanger through the hole into the engine compartment, then pull it through.
