I know I know this is probably not that right forum but I couldent find a better one to post in. I just have one quick question... for those of you that have installed subs where did you run your electrical cable through the fire wall? Im goign to be running 4 gauge to a 600 watt Kicker amp.

Okay .. here is the rule of thumb ... keep the RCA, Speaker Wires, and Power Wires sepearated from eachother as far as possible. This Is usually done by running the Power Wire is run on the same side of the vehicle that the battery is on, the RCA Wires on the Adjacent (Opposite) Side, and the Speaker Wires down the center. And Yes, you run the Power Wire through the Firewall of the Engine Bay, and remember to have an Inline Fuse on the Postive Cable no more then 18" away from the terminal .... I Hope this helps

running all the wires together can introduce noise to the system, or degrade the signal going to the amps, especially when the power wire is envolved.

Yea, but that is kinda a thing of the past. If you get good enough rca's now days they are all shielded and dont pick up any rf from the power line.i have a 2 gauge wire running by my rca's and i get no rf interference at all. Not a bad idea to run on opposite sides though if ur not sure if they are shielded.

easiest and hardest place would be remove the abs unit, and go through where the wiring harness goes through. if you dont have abs this will be easy, if you do removing it is a *****. Good luck
