running one visonik v4000xd right now on 12 volts at 1.4 ohms. meter a 150.0 on tl legal now, how much more do you think i will see on 16 volts at .7 ohms each with 2 v4000's. waiting for my batts to come in, but impatiently waiting, so i am trying to get a ball park figure.

well, I would say more than that if his subs will take it and arent to there peak yet. First off your going from 1 amp to 2 Thats double power, then he is dropping each to .7, Theoretically doubling again. Then going from 12-16 volts should be some more of a gain. at a guess I would say 6db.

if doing that would get you 6 more db there would be many more 150+ rides than there are now. it wont add 6 more db. id say he might be able to squeeze out 2 maybe 3 more
