I have been looking to upgrade my car stereo for starters. I don’t know anything about stereos except what I want them to sound like. C3 has been awesome, letting me listen to different stuff, and helping me find exactly what I want in my budget. :) The follow up is amazing and the products are top of the line. They really know what they’re doing and customer service is second to none! Can’t wait to get my home audio system going!
