I am fairly new to installing car audio. So ok here is the deal, I drive a scion Tc. And I have already done the big three upgrade, h/o alternator, and kenetik 1200 as the start up battery. I will be installing 3 kenetik 2000 batteries to power my JBL A6000GTI amp which will power 2 Fi Btl 15s. I know to hook up the batteries positive to positive and negative to negative, but that's all I really know. I want to add a 30 farrid capacitor, but don't know hot to set up everything. A diagram will help also. I also know to have a fuse within 16 inches of each battery. I need to know how how wire everything.
