Rear speakers audi a4

i wired my new after market radio but i dont get any sound and i was told theres a way to minipulate wires to go into the yellow plug to atleast get there rears to work anyone know how to do this?

could be a fuse, if not the wiring to the sensors. if both seem right, then the sensing unit has to be checked.

hi i have a audi a4 1997 and i wanted to know that what size socket do i need to take off the rear brake disks? many thanks

brian i am having the exact same problem, have you found a solution yet?

That's not a problem. It should function that way to keep your car from draining the battery.

If it's an analog clock, pull out on the stalk closest to it (the small one protruding from the cluster), and then turn it to the right - that will advance the clock.

im trying to upload a pic of the belt routing it wont let me email me i can send it to you [email protected]

Factory fitted sensors continous tone

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.
