Thanks for the help fellas definitely going to get a voltage meter today one that just pops in my cigarette light should right, I have a regular meter that I can test on my amp but as far as one to watch continually that should work right

Im running two 212's in 5 cubes at 32hz with a diamond d1000.1 wired to 1ohm and and old school eclipse 4 channel amp with alpine components in the front and arc components in the back I have a saturn ls with subs in my trunk. My question is do I need any power upgrade extra battery, big3, capacitor or bigger alternator? My headlights do dim a little when the bass drops any suggestions would be great
