Hi - unfortunately no. I wasn't able to get the factory amp working with the pioneer unit. I actually did manage to get audio from the new head unit coming out of the speakers (had both the new unit and the factory unit wired in at the same time - should have taken pictures because it was a ridiculous mess of wiring) but basically the amp volume was being digitally set by the factory stereo and when it was unplugged the amp would reset to 0 volume. Not useful.
At that point I got really frustrated and just replaced the amp with a new one.
It works great now, but I'm still annoyed that a perfectly good amp had to by bypassed just because it would only talk to the factory radio![]()
