I only used these guys for a fast service / tweak --- Josh, the manager was awesome. No fuss, no problem. There was a minor problem with a bypass switch from my installer (at a different Audio Express location). My Bluetooth wasn't working and I couldn't figure out why off the manual. They could not have been nicer.
I had trepidation on going in here based on the reviews; they were unfounded. They were kind and fast and hassle free. I'd go back in a heartbeat.
