once i get everything installed, ill be running 2 12" vmaxs off the JBL BP600.1 am i going to need a cap or better alt? im not sure if 600 watts is enough to do anything or not, please let me know! thanks
That JBL will take about 60amps at peak output. Which is quite abit of juice. And no a CAP is NOT going to do anything for ya but make the problem worse if your lights dim. Hook up the system first if the lights dim then upgrade your alternator. I would recommend atleast 50 more amps to whatever your car already has. Good Luck
