Alright man got a question. Im running 3500 watts in my truck got a yellow top under the hood with a powermaster 220 amp alt. I am always steady at 14v at half power and 13.5+ when slammin. Just recently(last 2 days) our temperature went from 15degrees to 33. My cap is now reading 11v! I know caps are shit and people dont recomend them but i got mine with the system so just put it in. I am curiouse though why I would lose 3 volts. I can even turn my subs off and have my 500 watt speek amp goin and still dip down to 11V. What do you suggest
