I've had my treg for about 10 months and had to have service performed on the stereo sys 3 times for the same problem. It seems that at times the bass response sounds much like wacking 2 pieces of wood together, very flat. Well the dealer replaced the amp on one occasion and just recently (yesterday) said after they put the car on the computer that it registered no faults but they did find I had the bass and mid settings about 3/4's or so and that they needed to be returned to normal levels...so does that sound like bs or what, I mean why would they even have adjustable settings that you can't adjust. Anybody have any idea on what the problem could actually be...possibly the sub or once again the amp?
