Jeep wiring question

[knotkrazy]

Hello all,

I'm installing an aftermarket system in a 2005 Grand Cherokee. So far, so good; but I need to route a 4 ga power cable through the firewall to feed the amp and sub. I see an unused grommet below and inboard of the brake reservoir; is that a possibility?

I'm sure this could be better handled by a professional shop, but I have an engineering background (not that that matters here) and am having a blast installing it!!

Any ideas or guidance is sincerely appreciated. I'm taking pics as I go and will post the entire build when finished. Thanks in advance.

Pioneer DEH P6000

Polk Db 651's

Infiniti Basslink

Audiobahn 4004T amp

I had the amp and sub from a previous install; total out of pocket, including shipping, cables, wiring, etc, $550. YEAH!

Any unused grommet should be just fine. Just be cautious of high heat in the general area and make sure the wire is kept away from those high heat areas.

I have an 05 GC also.

I installed a remote start a month or two ago and could barely squeeze 4 small wires through the factory spots. I don't remember seeing any unused grommets. I have a Limited 5.7L though so maybe theres some upgrade that you don't have which is why its there?

From what I remember there are two small factory grommets around 6-8" below the brake cylinder. One has wires through it (the one I used) and the other had some tube going through it I didn't bother following it.
