i agree with the other review. they suck. they tell you all these things then when you come back they act like they don't know you. they are very arrogant. I shopped around and found Whole Sale Car Audio in Pittsburg instead. they are cheaper then GM electronics and they have great customer service. and they have a room that you can hear how the speakers sound. its pretty cool. I'd recommend that place then GM. but either way shop around and pretend like you don't know much that way you know if they are ripping you off or not.
