I used a custom wiring harness made by Autoleads in the UK. Unfortunately, they apparently messed up the 12v constant and 12v ignition. also, i had to run the remote amp power manually.

i checked the voltage on both, all the way from the wiring harness to the sled, and both are correct (after switching them). the unit still goes off completely when the ignition goes off. i don't hear any 'thump' though.

i am running 2.0 final with hijack 334.

btw, this is an audi (obviously they are similar, if not the same - just clarifying).

any other ideas?
