    Is ist possible to remove the amp and sub but use the wiring to power an aftermarket amp and subwoofer ??? I have a 12 inch sub in a box with the amp fixed to the back if the box, just wondering if I can tap into the existing wiring to power it.

    Thanks Andy, I fitted the stereo today and the iso lead, tbh it sounds like the whole lot wants completly ripping out and starting from scratch!!! The fronts are MEGA loud and the rears REAL quiet, just cant seem to find a happy medium using the fader on the head unit, sounds very harsh...

    The fronts will be louder than the rears as they are running off the HU which will now be delivering 2 x 50w+ while the rears are still using the feeble Audi/Nokia amp which is 2 x 20w. You need to replace the fronts with some decent components - JL Audio TR650csi's are decent and fit a sub, then ideally run the fronts and sub off a 4ch amp, and rewire the rears to the HU for when you have rear passengers. Makes a world of difference
    You can then ditch the ISO harness adapter and run proper RCA's
