    Navi head unit/ amp and sub question

    I just instaled the avic-u310bt from pioneer. Its great! I got everything to work but the sub/amp. all the wires have been ran. the remote and power down the right, gps and rca on the left. I had to tap in power from the steering column as well for the HU. first off, when I turn the headlights on, I can hear the humming of the alternator im guessing? anyhow, its annoying and I dont know where to start. To get rid of it. (this is without the amp/sub plugged in)

    second, when I plug the amp/sub up, the rear speakers get a mad crazy feedback noise, I've never had this stuff happen before. Also the HU has two outputs on the back one is for left and right front, the other is for rear right/left AND sub out...I put a Y splitter there for both, at least thats what i was told and thats how i wired it..

    One last thing..when I turn the car off/on the speakers pop really loud even with the volume at zero. with and without the sub/amp connected.

    FINAL question...where is the radio anntenna? does it come out by the fuse box on the drivers side by chance? I saw a thick black wire cut and taped off right there and my radio doesn't work at all, even with stock HU. I figured this could be it? (i just bought this car 2 weeks ago, comming from an E36 bmw)

    suggestions?

    I want to make sure I understand your situation.... so, you chose not to use an aftermarket harness adapter from Connects2 or Metra?

    I used the one from Metra. I had the symphony two unit with bose upgrade...the owner before my added some parrot bluetooth thing, so it had an extra harness...took that out, plugged up the metra stuff...no power, nothing turned on. after wondering what I had done wrong I realized there was no red power wire from the car..I went to see a friend at best buy, he said you have to tap a power wire from the steering column..we tested wires, found it, and i tapped it...everything was on and working! so right now everything works except for my aftermarket sub/amp and this annoying whinning, especially when i turn on my headlights. The other problem is I get mega feedback when i plug in the sub, and everytime i turn the car on and off the speakers pop pretty loud.

    Sounds like whatever you tapped into is causing the issue! Most of us use the wire from the aftermarket HU for the amp switch. In addition, the newer A4s provide the ACC signal (switched 12v) from the CAN-BUS.. so no RED wire on the harness. You need to purchase another adapter (Connects2 or SWI-CAN) to provide the switched RED ACC wire.

    Re: Navi head unit/ amp and sub question

    hmm, is that going to solve the amp/sub issue as well? I tapped that wire because a guy with an s4 told me to, ha. So there is two harnesses comming from the car, both have something in them already with the aftermarket HU, with yet another harness for power, where is it going to go? im not sure what the CAN-BUS and the SWI-CAN are either..and I just used the blue wire as the remote, which is the same thing as the amp turn on im assuming?

    If you have a B7 or newer, then you have a CAN-BUS. I'd recommend spending some time getting up to speed on the Connects2 product for your car.

    Usually the blue wire is for the antenna booster turn-on and the blue/white wire is for the amp turn-on.

    You can also ask Enfig to build you a plug and play harness for clean install. Contact Mike @ Enfig if you want to go this route.
