I realize this is almost a year old, but I would like to know if you added the amp to your truck and if so, what are the details of the install. Also, did you do anything about the door chimes as far as being loud?
I've got a 22 refresh Denali and am gathering stuff to do the same thing.
BTW, I have ordered from John at AIS and I have to say he is excellent to work with. Very good quality.
Thanks!
Jim
