ok so i figured id give em a try and ordered a h/o alt from db electrical. suppose to be 200a at 1200 rpm n 105a at idle, but wats idle to them? im running a sundown sae 1200 v2 at 1 ohm so around 1500w rms. when im driving down the road the most ive seen voltage drop is about .5 volts on very low hard hitting songs. that part is wat i do like. wat i dont like is when i pull up to a stoplight or stop sign voltage sits at 13.1 with nothing on, 12.6-9 with my lights on. if im in park at idle voltage will sit around 13.9 but if i do anything, roll down a window, turn on the air or heat it drops dramatically, windows pull it down to low 13s(thats one window at a time, rolling down multiple windows at idle kills it brings it to like mid 12s. n air or heat put me at about 12.7. but jus the weight of my foot on the gas puts it at 14 is there anything i can do to better it at idle? the alternator shop here said i cant go any smaller on the pulley because there wont be enough surface area for the belt. i really like how the voltage is when im driving but im concerned that im going to kill my batteries(stock duralast upfront and kinetik hc1400 in the trunk). i just keep thinking of senarios that make it seem like i should just get my money back, run stock alt, and just set turn my amp down. i was thinking wat is goin to happen on a really hot or cold day. i dont think ill be able to run my a/c or heat at idle without draining my batteries which really sucks cause it gets f'n cold here in the winter and now its gettin f'n hot. wat would you guys do? got til next tuesday to send it back for full refund
