Well I can't decide if I want to try to wire down to .25 or just stick with 1 ohm for daily. The amp is a db drive pt 2000.1 and anyone you ask says its a monster. I've heard of people running it at .33 daily. For electrical I have a sprinter 100ah under-hood, a 134ah c&d in the back, big 3, and I will do 2 runs of +,- to the back. Is this sufficient enough? Apparently the amp is pretty under-rated and its been modded to run 16v (not that that probably matters).
