what are capacitors normal voltage level, i have a bad feeling its not supposed to read 15.5 - 16, which mine does(1 sub amp, 1 speaker amp, a cap, and deep cycle 4 extra power in the trunk for long playing without car being on (aka: camping)), my friend started asking if i had the power wire hooked up in parallel or in series, i was totally lost..haha

I'll post a picture of my setup tomorrow if it helps
