The speakers that come with your AUDI are powered speakers that have a base speaker built into the back of the standard panel. This is why there are additional cables going to these speakers. You will also need an ISO adapter to connect a third party head unit to the standard leads as the standard fit stereo has power sockets and extra sockets which are unique to Audi and these speakers.
This job requires a good knowledge of refitting electronics, it should be left to a AUDI specialist. If you want it simple and quick then just remove all the speakers and additional equipment then use an ISO adapter at the front to send the signal to the speakers by simply using just 4 wires from the loom - you will have to select the wires yourself with and ohmmeter and add to them end connectors.

    Not necessarily - you can use the wires already present, just that you must change their destinations and purpose.

I have an 01 audi a4, and i wanted to change the rear speakers. i remove the right one and its simple, two wires, but when i remove the left rear speaker there's 8 wires and was wondering if 2 of the wires...


as long as it is audio out then you cant go wrong. same power from your stereo on you deck you get and will be dividing all the power like sharing each other. parallel connection is the best one . but not much as when you hooked it to an amplifier. auxiliary is different which is another option like adding more components to your car.

Audi A4 driver door no power


A typical problem for the newer A4's. The rubber tube that goes from the body of the car to the door will flex enough to short the wires out. If you remove the rubber boot and slide it back you can inspect which wires shorted out. I am 99 percent sure this is your problem, I have seen this in 4 other a4's. Hope this helps!

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!

Rear speakers in audi 1999 audi a4


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.

1998 Audi A4 Quattro rear speaker wiring


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.
