Q about HO alts

I have 0g and and a 4g (don't ask) coming off the front battery to back battery. Front batt = stock back = deka 9a31 equipment saz 3kd and kicker 650.4 as I stated b4 did Big 3 in 0G long time ago. All wire is knu (good stuff) copper and 4G is tsunami. Voltage dropped to 13.2 lowest I believe, but thing is I bumped at my usual 24\49? not sure the highest never turned it up past 26. Was fine, then a couple days later volume no more than 20 the voltage started dipping real low whenever I turned on the a/c. Low as in 13.1-13.3, then a day or two later it would stay at that voltage with no music on. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I had to rev it to 1100-1400 ENGINE rpm to stay at 14.4. (no load, and yes batts fully charged) After the a/c voltage dropped i charged both that night. But the before i noticed the voltage dropped (have stinger lcd in car) I opened my hood one day to clean the engine in the morning and the alt was kinda but not get crazy hot from only 20 mins of driving. *sigh* I just hope he over built it this time so nothing happens again. **** this is getting long! Deka is about 4 months old, brought brand new and battery is about 1-1.5 years old. Sry for the late reply have to work :/
