Thought I would throw this out there... If you have seen the installation work of Neils GLi and his custom sub box this is the place to get something similar done. They also have Home Theater electronics too - this is not a best buy store by any means, only moderate to high end equipment but at similar pricing that you would pay for the junk that the large chain stores sell equipment for.

 Two locations: Winston Salem and Greensboro
