The rear speakers are amplified with the amplifier attached to the driver rear speaker.
This probably means that all necessary wiring to trunk.. power, ground, remote lead, and speaker outputs are readily available already in the trunk right??

If this is so.. wouldn't it be possible to just use all those wires to integrate new speakers and an amp in the back.

Does anyone make a wire harness kit that separates this for aftermarket??<p><a href="http://registry.audiworld.com/audi/registry/details.asp?car=4329"><img SRC="http://www.netdrive.com/MyDrive/get.jsp/%7Elchao/My%20Pictures/chaotic-s4.jpg" BORDER=0></a>
