Well I just got finished, took me about 3 hours. I took my time though, wasn't in a rush. I tested it twice before I put it back together and the sound is perfect.
Two hints for anyone reading this that hasn't done it yet.
1) AT install: lifting the chrome piece, make sure you have your screwdriver properly shielded, I scratched my plastic even with using electrical tape. This piece is not held down using clamps, instead it is just wedged in there with tape/foam.
2) The clips in the back of the HU were tough. I think the instructions would help if it gave hints on which pieces to take off first and where to pull.
-1st should be the hazard clip, but use the clip on the inside on the HU.
Otherwise the instructions were very clear and perfect for most people. Thanks again for the great overall package, worth every cent.
