This is aggrevating the crap outa me. I just installed my audiocontrol eq/xo/line driver(3.1i). I installed a comp set of 5.25s (Planet Audio). The comps sound great, but I got a lot of noise. Everything else is wired right eg. HU, amps, & speakers. The XO (it is an in dash mount). Well I have it grounded to the HU ground. Is that my problem? In a 2000 Ford F-150, where (behind the dash is a GOOD solid ground? I did NOT have the whine before I installed the XO. I even messed around with the jumpers. No luck. Isaac, Jonathan, ANYBODY? |

You could use a relay to isolate your hot lead. Get your power from the battery, not the dash. AC's have always been a bi*ch to work with in noisey electrical systems. |

This is hooked up to an amp, right? if so it could be an rca problem, try unhooking the ones to the amp one at a time to see if it is that, try rplace the one from the head unit to the 3.1 and switch from front/rear input. try a ground loop isolator from radio to 3.1. |

actually, did it have noise before you put the 3.1, if so, double check ground at amp. |

Ext cab. I put a box on stilts right behind the driver's seat with the back seat in the upright position. I had NO noise before installing the EQ. |

well then it has to do with connection to head unit, I have this uniot and have no noise. switch rca from radio to 3.1, unplug rcas one at a time to see if you can get noise to go away, it is a porcess of elimination, if you have a spare rca, jump from 3.1 to amp and see if it still does it. |

Somebody else put this HU in. I found ALL the grounds "daisy-chained" off the HU. About 4 of them. I am going to shorten the grounds, then run 18" of wire to the frame at the firewall/tranny cover. If I drill a 1/64 hole & put a small self-tapping screw in the cover (for the ground) do you think it could alleviate the problem? Also, I can't see the top of the tranny really well from underneath-any pointers on anything important that may be up against the chassis? The RCA cables are professional competition grade. $90 a set. I know I got ripped, but the cables are top shelf stuff. I got a ground loop isolator going into the mids/highs amp. Noise is still there. Not near as bad, but there. I am gonna try a new ground tomorrow. |

I have worked fixing this problem more times than I would like to remember. Fords are nortorious for this problem. The fix will lie in the grounds. Try running all together behind the HU/EQ in the dash and use a larger gauge wire to a real ground spot. To verify it is good take a reading at your ground spot for your amp and the positive of the amp. Then take a reading at your new ground spot for HU/EQ and power of the amp. If they are the same you should have the problem gone. If not, then take the grounds to the same spot as the amp. |

I think Fords have a tiny static ground gauge wire...mine is around 8 gauge I believe? Pretty sad. I had to upgrade it. |
