took my 2006 ford super duty in to extreme originaly had and alpine deck alpine speakers and jl amp. i was not happy with the alpine head unit so i got a touch screen pioneer put in and i loved it after about 4 months of driving my truck the passenger door tweeter popped out twice revealing to me that they used butt connectors to make the connections. the original reason that i sent it in was because going down the road i couldn't hear the radio. and after several thousand dollars it was no better, so i took it somewhere else and found out that one of the speakers was wired reverse and they never tightened down the rear seat bolts down all the way, because the power lead was run under the seat frame. also the reverse camera and radar jammer wires run underneath were run in the frame no loom or protection just bare wire and they were zip tied through frame holed where they would have rubbed through . moral of the story nice building nice people doesnt mean they know how to install
