Hey, I've got a powerful stereo in my Eldo, and I've been having problems starting the car ever since the stereo has been installed. I checked with my mechanic, he said the battery is good (one year old Optima Yellow Top) and that the alternator is charging. He thinks that since my car is taking so much power that the alternator can't keep up. So I'm trying to find a high power alternator. So does anyone know where I could find one?
