Casablanca Car

I brought my car to "car toys" to have a box rebuilt to allow for more space. They "had to" re-wire" the car which ended up frying my Amp twice. The box they built was nothing like what I asked for. they were pricy as hell and talked shit all day about the first guy who wired it (who just so happened to win better then 30 car audio comps). In the end everything was blammed on a type of sub that has not had problems since I re did all the wiring myself. anyone else have problems like this with them?
two stores in colorado. I had to go to a different one to get my problems fixed cuz i wanted to kill the cocky SOB at the first store. While the second store was better, it wasen't "good"
