I'm putting in new rear speakers. I have taken out the rear seat backsand popped off the shelf. Then I placed in the new brackets to allow me to fit universalspeakers and screwed in the speakers (to the brackets). However theleft rear speaker has a large connector block which i have never seenbefore with about 6-8 wires attached to it. This will not fit the newspeakers (they only require 2 wires). However the rear right side does fit the car as it only has 2 wires. How can i fitthe left side to the speakers? P.S i also hav a new head unit

Re: 1999 Audi A4 Rear Speakers
The large block is a factory amplifier - in your car (as was in mine) you had a partially-amplified system. The front speakers were driven at speaker level from the head unit, but the rears were fed a line-level signal from the head unit to the amp, which then boosted to speaker level. The harness then sent the speaker level signal to each rear speaker.
What you can do is fit your new head unit. The fronts will interface perfectly with no issues. For the rear, run new wires from the adapter harness at the back of your head unit, back to the new rear speakers, and connect them directly. Then everything will work as it should.

If you mean the rear shelf removal, then you begin by removing the rear seat (lift to release the corner clips on each side holding the cushion to the floor). Then remove the fasteners for the seat belts, then lift the seat back to raise and release it from its clips, and remove it from the vehicle. There are then a lower and upper trim panel around the back shelf that you need to remove (these may be on each side of the shelf, e.g. they are called 'quarter trim' panels). Then you will see some push-pin fasteners that hold the shelf across the front lower edge, so you gently pry out the center push-pin of each one of those to release the fastener. Then you pull the shelf forward to release it from the clips that hold it under the window. Then remove the wire to the center high-mounted brake light. The panel with its speakers attached can then be removed, but also remove the wires from the speakers so you don't break those. connections. That is the procedure as shown in my '98 manual.
I have a similar problem on Audi A6 2.5 tdi year 2000, is just that my subwoofer is working fine, but the rear speakers have no sound and the rear satellites on the same ciruits are working just fine, I cannot explain this! I have taken apart the rear speaker and teasted with an ipod and one is working fine but the other is dead! I don t know if there is any connection, or there is a filter for the rear speakers and if one speaker is dead there will be no sound on the other speaker! but as i said on the same cables satelites are working well!
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!
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.
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.
First remove the rear seat bottom cushion (grab the front edge roughly in the center of each seat position and pull up firmly, and it'll unclip and come out). Then fold down the rear seatbacks. Now, the side bolsters for the seats (between the seatbacks and the doors) have to come off. First, pull down strongly near the bottom (there's an upward-facing hook there that clips onto a ring and holds the bottom in place). Pull down and forward and it'll come off. Then slide your hand about 75% of the way up, and pop the bolster straight forward to pop out a retaining clip. Finally, you can remove the top of it from its mount, and you'll have the bolster out. Repeat for the other side.
Go into the trunk and look up at the bottom of the rear shelf. The harness plug for the third brake light is there - unplug it.
Now, back in the rear seat area, just grab the front edge of the parcel shelf and lift upward to pop it loose, and the whole thing will slide forward. Then you can remove your speakers.
