1999 Audi A4 rear speaker replacement

Hey I took out my factory speaker covers and speakers to find a small black clip with the positive negative speaker wires, Which i could cut the wires by the black clip and then connect teh to my new speakers. Not a big deal. The left rear speaker has a big blue block with and 8-pin insert, There are many different colors running into this blue block. My 6-disc changer doesnt work and my factory speaker had the amp on it. I wasnt planning on purchasing a new amp or a 6-disc changer. All I want to do is listen to my new speakers. I'm not sure what the other wires are for or what color my left speaker positive/negatives are. Can anyone help me out?

You can't use any of those - the large connector at the OEM speakers is because the rears are amplified. Your factory head unit puts out a line level signal to the rear speakers. There's an amplifier on the driver's side rear speaker (the box around the magnet that you can see from inside the trunk).

You need to either replace the head unit with an aftermarket one to drive your new speakers, or you need to tap into the amp connector and find the line level wires, break them out, put RCA plugs onto them, and plug them into an aftermarket amp, which you'd use to power your rear speakers. Doing it that way allows you to keep the factory head unit.

You don't want to fit that - it's the factory amplifier for the rear speakers (the rears are amped, the fronts are not). You need to run new wires from the head unit back to the new rear speakers so that the speaker-level outputs from the new head unit are used to drive the new speakers.

SOURCE: A4 airbag sensor

A4s are known for airbag lights due to the bag in the side of the driver's seat. The yellow connector under the seat gets stretched and opens up partially if you move the seat too far. It's just a quick opening but it's enough to trip the light. In mine, I ziptied the connector tightly together, then turned off the light (you need the VagCom diagnostic software for this).

SOURCE: WHERE IS THE NEGATIVE BATTERY

Hi, When jump starting this vehicle make sure that the Q7 is connected first, then connect to the jumper vehicle. Connect 1 lead to the positive on the Q7 and the negative to a good solid body part or engine part. This will then ensure that the vehicle will start on the jumper vehicles battery directly without going through the Q7 flat battery causing the electronics to strain.
Hope this helped.
Thanks
Jason

Hi, there is a factory wire (red with a black stripe) in your car for illuminating the stock radio. This wire is not to be used in an aftermarket radio, so you need to make sure it isn't connected and also isolate and bare wire with electrical tape. Please let me know if you have questions, and thanks for using FixYa.

Retro fitted radio


i believe that car has a pre-amp in the rear speaker setup, but the clip should work fine, i would return it, they do have a 10 percent failure rate. Nothings wrong, there's just a lack of signal. If nothing else works you may have to run speaker wire from the deck to the rear. Its not bad, just takes some time and common sense, as long as you are comfortable doing that stuff, most of the platsic around where your doors go is simply clipped into place, and can be removed and replaced with relative ease, run the wires for both spkrs on the same side, get them in the trunk, and hook them direct to the speakers themselves. Good luck!
