This thing is a monster...weighing in at nearly 40lbs ...It will be shipped double boxed and insured...Basically brand new condition...$700 shipped lower 48
It does around 4000 on a 12v system at 1ohm and around the 6500 on a 16v system at 1ohm...I have heard of these being run at .5 daily with a strong electrical....my guess at .5 it would be close to the 6500 on 12v's from what I've read on these....I'm getting my Z1a's in and just trying to make room....
