for anyone with a system where did you put the hole in the firewall so the positive cable could get to the battery? pictures would help alot

I think if you pull the carpet back there is a hole on the divers side. I will look around and see if I can find more info or pics.
If nobody else anwsers.

There is a half inch plug behind the brake booster that you can run 4 gage wire through.

do you happen to know which wires (by color) go to which speakers, i need to find out the two rear speakers, left and right

I'm sorry, cann't help you with that one. :roll:

Couldn't you just look at the wires that are conected to the speakers to see what color they are?

how do i get to the speakers?

Get a saw and cut through the door panels. Just kidding. You probably have to pop off the door panels. Thanks for the info on the hole. Im getting ready to install some lights and will need to run through the firewall as well.

The twisted wires are always the speaker wires. And if youw ant to know which speaker each wire goes to....carry a batter with you and touch it to the positive end....you'll know...

I ran my cable through the hole mentioned above.

Shift,
I don't know your skill level with installing stereos, but from reading your posts I suggest having a friend help you or getting it done professionally. I am not trying to put you down or anything so, but I wouldn't want you to mess up any of the electrical system and void the warranty. It's a little more involved than say, putting on a new grill or intake.

Well that is some good advice....there are a TON of wires back there. You have to peel back the insulation to get to the wires...then you have to know really what wires you are looking at. Generally the speaker wires are twisted. Some new cars can't even be changed with out a complete rewire of the system. Some even have high tech wireing. Titan was pretty normal. However I have a whine in my amp that I can't figure out for the live of me....so forget everythign I said!!!

thanks for the help guys... but i already installed it, i just had to use my brain a bit... i havent hooked up my 2 10s yet but i have 1 12 in it just for now and it sounds pretty good considering it is an old speaker.
