I need to have more info about how you installed it, did you use rca wires from the radio to the amp.? Make sure the sub setting on radio is turned on. Make sure rca wire are in the input connection and not output, also check you connection from radio that they're in rite place. I really need more info about the map of your wireing

Should be a standard 8" sub, located in the passenger rear side. Remove the plastic interior body panel, the sub will be located behind. Remove the 6-or-so screws holding it in, disconnect the wires, making note of which wire connected to which terminal. Connect the wires to the new subwoofer, replace screws in new sub. Test the audio system to make sure everything is working properly, and re-install the plastic interior cover panel.

Thank you for using FixYa, have a nice day.

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!

While the rear subwoofer does fail, it is often misdiagnosed because of a rattle in the vicinity.

Try removing the little fold away hooks near the subwoofer (philips screws) and see if your problem goes away.
If it is still there, loosen the panel and see if it goes away.
If it does not, more than likely the speaker has in fact failed.

Most subwoofer buzzes have been either the little fold away hook or the wire harness just behind the subwoofer.
Actual speaker failures are much more rare.
