Most auto custom sound shops carry them. I think circuit city does too. If you or any friends have delt with any of these shops, and found them to be stand up, check with them. If you get a 1 year warrenty you should be good. Just make sure the shop will stand behind it and not make you return it to the manufacturer. I had one from sears years ago. Exact same unit that volvo used in the 80's. You could prolly find one of those at those at a upulit. The last one I bought was from a local sound shop. Worked great for 2 years till i sold the car, cant remeber the name
