Yesterday I had a problem with my 3. I stopped to get gas and when I got back into my car it wouldn't start. My lights wouldn't even turn on. A buddy I work with passed by and saw I had my hood up and stopped to help. We tried jumping my car and it started after some coaxing but when I turned the wheel to get going the car died. We tried jumping it again to let it charge but couldn't get it started again. So I went to work reluctantly leaving my car at the gas station. After work we went back with some tools and checked the battery which was good. I started pulling off my Buddy Club Condenser and my amp power supply to see if those might have been the problem. Sure enough right after I pulled off the Buddy Club the car started up like brand new. I sent an email to Buddy Club USA since it's only 3 months old and I have yet to hear back from them. We'll see if they'll send me a new one. Until then it's definitely not going back onto my car.
