As are you LosIsATool! I now have one 12V+ 0AWG cable from the pos battery post and will soon have another 0AWG cable from the neg battery post, so it's a good thing I'll only be running 100W x4 and 75W x2 and 500W RMS subwoofer, so I should be pretty good! But the real source of the electricity necessary to run everything electrical in the car is the alternator! So improvements of the car's own 12V+ and GND to the alternator's + and - terminals AND the battery(ies) are best for super high power audio systems, which mine is not!
