I just spent a little under 15,000 bucks for a mobile system which unfortunately never sounded right. It was constantly out of tune and was never properly finished. So I brought it to some shops in town but never really got anywhere. My last stop was notorious motoring. Made an appointment and when I showed up dave greeted me. I was very excited to see him. We had worked on a couple of system builds together in the past (me as a customer of course). Dave's whole approach is to install what the customer wants not what the builder wants. Getting back to my review, when I told dave what was happening with my system he looked at it and quoted me 3 hours. 3 hours later he called and said he was finished. When we got in the car, put a cd in and Blam!! The system was sooo loud and sooo crystal clear it felt like the band was playing right there on my dashboard. I'm happy notorious picked up dave while restructuring the install department. All I can say is that we can look forward to some amazing builds coming from dave in the near future.
