hey thanks you guys i had posted a thread stating my car wouldnt start. well i came home and it wasnt starting i fully charged the batteries. and the car started, then i checked the batteries it was giving me 12.5 on volt meter not running then i started it and it was giving me 14.0 steady it wasnt dropping nor going any higher, i never seen this. i had turned on my a/c and it stayed at 14.0. but when i turned up my 3000 watt system and had it hitting hard it droped down to 12.6 volts could it still be something wrong like the alternator not giving it enough charge or something still wrong with the batteries not holding a charge?
