[QUOTE="bgowdy, post: 8314850, member: 632121"] hm... kinda odd. My last build was using a 220a dc power alt, with a Crescendo Bc3500 @ 1 ohm, with 315ah batt bank. i had 4 runs of CHEAP CCA 1/0(install bay [IMG]//content.invisioncic.com/y282845/emoticons/suave.gif.858fc102f7646e678ee8af7e1fbc41d1.gif[/IMG]) 2 pos & 2 neg front to back. I could run full tilt at idle rpms and would only drop to about 13.3-.4v from 14.3, and at 2k rpms i would only drop to 13.8-14v from 14.3. Sounds like a ground issue some were or maybe try adding another run of 1/0? [/QUOTE]
