Yea this one really sucked ! The amp is located under the air bag.... to the metal bar support for the dash. If you look behind the glove box (only a few squares) you can see a silver box and that is your amp. You will have to drop the glove box to get to it... the only problem is that all the pieces overlap starting at the drivers under dash so all that comes out and there are 3, 10mm bolts that hold the amp.... one is all the way to the left and not so easy to get to with a rachet. hope it helps... i could not find a harness for integration... not saying much cuz I work for corporate so that means i cant order anything.
