How the hell do you get the back units out as an assembly??? I can see that the speakers come out individually but what about the amps???

 

front or rear?

 

I assume that you have BOSE, since you got amps, for the front, just remove the screws around the the whole assembly, then unplug the harness, for the rear, you will have to remove your rear seats, then remove the rear dash cover thingy(sorry, don't know what its called), thats the one with your speakers cover on it in the rear, right under the rear windshield, then you will see like four bolts holding the assembly together, remove that and the whole thing will drop.
