Hello My amp works good in my car as long as the volume is low but when i turn it up the green light starts to dim and the sub cuts out. I tested my voltage and it is 13V when the unit is off but when it is on the voltage drops to 8.4V this is when the sub cuts out. would a better battery help? Or does anyone have any suggestions? I already have a capasitor and that didnt help
bad battery and/or alternator. turn the car on and test the voltage coming out of the alternator with the music high. if it dips below 12 you might have a problem with ur alternator. caps only hold the charge for a very brief loud sound. try a friends battery. if that works, i suggest getting a optimum battery. they are kinda expensive, but you will definetly see a big difference.
