You might look at the outside of Audio Concepts and think that their small location equals limited choices. I have not found this to be true. I have purchased several vehicle audio systems there for our sons, and have been pleased with both the selection of audio choices and their sales and service.
They took the time to diagnose a small but aggravating problem in one son's speakers that made them work intermittently, and coached another son through removing his system safely and carefully after he wrecked one car and bought another one.
I would definitely use them again.
