Where in the Firewall is a good place to drill in order to run power wire from the battery to the back...thnx again

 

I hooked up a 480 watt amp in my trunk and ran a massive power wire, and there is not reason to drill a hole... If you will look under the hood, right about in front of the steering wheel, you will see a black rubber gromet with wires going through... I suggest using a coat hanger, poke it through to the inside, but only go in about 5 inches, then lay inside your car and look right up under the dash, you'll see it, tape your wires to the coat hanger on the outside, and then pull them through to the inside. I have the sterio wires, and wireing for all three gauges running through there, so it should handle everything you put in it...
