from my trunk to my dash and my battery what is the best route. i need this info asap thank you
my power wire for the amp if run threw the left side of my fire wall there is a small rubber grommet just to the right of your battery ( when facing the car) comes out behind my glove box then run down the bottom of the door, under the plastic trim, my ground wire is bolted to the little bolt that holds the bottom of the back seats in place, my rca wires are run down the driver side of the car.

Yep, best to use the grommet behind the battery and run the power down the passenger side. Send the RCA down the driver side. If you run the RCA right next to the power wire, the power wire can introduce noise into the system. You want to keep them separated.

I have my power running thru that same hole, ran thru the passenger side floor right next to the center console. RCA's and control wire are on the driver's side floor next to the center console.

I see this a lot in amateur installs. Don't do this. The threaded piece is tack welded to the piece of sheet metal that is in turn tack welded and glued to the rest of the unibody. What you want to do is use a metal tapping screw and a star washer into the rear frame rail. Clear away all the paint with a wire brush attachment and a drill.

is that the bolt on the trunk floor on the left side of the hatch?

I was talking about the bolt that holds the rear seat down. You're asking about the bolt that holds the bumper to the frame rail. That would be great if you scrape the paint away and have a ridiculously huge ring terminal with a small enough gauge and some monster crimpers. You may also need an impact to get it off.

Your avatar of Sarah Palin makes me want to puke. You are one sick bastard my friend.

As mentioned, it's best to run the power and RCA wires down opposite sides, although in my 240 I ran them side by side and had no issues in terms of noise.

ground

if you run the ground to your back seat bolt you may not get the correct circuit. the best thing to do is ground it straight to the frame or even grind some paint off and use a self tapping screw that will give you a very good ground less work for your amp:))
