lanman31337 Posted July 17, 2009 Report Share Posted July 17, 2009 Absolutely. Get a multimeter, set it to turn caps lock off, then turn it to ohms. You'll want less than .5 ohms from point to point if you can. First, run a dedicated ground to the rear battery to feed your head unit. Does your EQ have constant, remote and ground, or just ignition and ground? The factory tire jack housing is piss poor too. You need clean chassis, not things that are just tack welded onto the body.

8000watts Posted July 17, 2009 Report Share Posted July 17, 2009 my headunit is grounded of the wiring harness wherever te factory harness is groundedwhat if i power the eq off of the power antenna output of the headunit or just splice it in to the power of the wiring harness im going to move the ground back where the he unit harness is my amps are grounded to the battery less than 3 feet the second battery is grounded to the frame by the tailight and to a bolt that secures the factory tire jack housing did u sand and make that ground urself or was it jsut a hole that was already there?? sanding helps u get ALL the ground...wat i did wit my eq was basically run that straight to my radio...power to the radio's power, remote to the power ant., and ground to the radios ground...dont kno how others feel about that but it works perfectly fine to me! u should try that and while ur shit is still ripped out of the dash, (so u dont have to take it bak out if it didnt work) turn it on and check it out...

lanman31337 Posted July 17, 2009 Report Share Posted July 17, 2009 Start with the stock ground for the radio. You're running an aftermarket setup, so ground the head unit, the eq, and the amp to one central clean spot. VERY clean setup for the eq by the way. Another trick, since you're running some wires, once you get them to the back, twist them around to make it a little neater.
