I ran into those problems a couple times.

1st time was at school they:
1. Smashed my drivers side window
2. Fubared my dash trying to get my deck out(had it bolted in so they bent the sides of the deck and i had to take it apart to realign the case so i could get cd's in and out)
3. Ripped out my rockford 800a2 amp

2nd time they did it at a repair shop
1. Smashed my back passenger window
2. Took apart my dash nice and neat.
3. stole deck and unpluged wireharness
This wasnt that bad because shop paid for a new deck and replaced the messed up dash from the previous time
