I feel your pain. My wife bought me the HU for Christmas and the morons at Circuit City installed it for free as part of the package deal she got when she was there. So, I park the Trep outside, give the guy the keys and they tell me that it'll take around an hour. Fine. My wife and I go to another store across the street to do some shopping etc. An hour and a half later we go back and the car is again parked outside so I go get my keys, ask if everything is ok and when they say yes we go to the car. Once inside, we notice that the CD doesn't produce sound, only the FM/AM does. So I go back asking what's wrong. So I put the car into the garage they have and leave it there again. A little while later I come back to find the Trep outside again, confident everything's ok. Well, the HU plays and everything is good with that, but every single light on the gauge cluster is lit up, the odometer reads "no bus", the tank is on empty etc. So they pull out the HU again and find a wire or whatever that they haven't covered in tape and it's apparently causing a short-circuit. Unbelievable. Finally everything is ok and we leave. Now, for the last couple of weeks I've had trouble with my rear speakers having a lot of static and sometimes they simply don't work. Other times they play like nothing is wrong. So now I have to have my regular mechanic (who's incredibly sloooooooow, but very good) fix it. These people take no pride in their work, you're messing with somebody personal possession and you don't care if you do a good job AND you're getting paid for it? It's the last time I'm having anybody like that touch my car. The next time they'd probably set fire to it.
