my mate runs 9k off a stock alt and like 5 batterys..it can be done,(edit: he wont play music for long, jut short bursts maybe 1-2min, but is gonna run a HO soon)
altho i think i read OP had 2 standard alt? correct me if im wrong.
and you can still get very stinky if playing decaf lol iv found this, some songs will, some wont.
could be at 2ohm, but still, dunno why it would get so hot at 2ohm..
