I had a subwoofer with a bad amplifier and was having a tough time getting support from the manufacturer so I decided to find a local company who could help. The guys at Arizona Hi-Fi were willing to inspect the amp and repair it if they could. Well, a couple days later, I got a call saying it was fixed. They easily saved me HUNDREDS of dollars since my next step was to find a replacement. Everyone I worked with was very courteous and easy to work with and I would not hesitate to go back to them for additional repairs or to replace any of my existing equipment. Great job guys!
