Anyone looking for an upgraded sound in their A4? I have for sale a 'kit' of sorts. All speaker wires & remote wires are the correct length to be ran under the interior trims of the car to mate up to each speaker wiring. When everything is clicked back into place, completely 'stealth'. having an aftermarket head unit is a MUST as this needs remote from head unit to amp. Splice right into your stock speakers (bose/symphony) and get more sound! Or run to aftermarket speakers, works just as good, if not better.

-Rockford Fosgate Amp (Punch 500X) 62.5 RMS X4. (not a cheap amp).
-Thunder cable intensifier series.

Please feel free to PM me.
