I picked up 4 SAZ-1500's for a great price all are V2's
I only got two hooked up right now, ran out of 8 ga, but my score went up a tenth just by a direct swap out.
We clamped a little over 4k out of the pair strapped at 1 ohm.
Reason I picked up the 4 I can either wire them to 2 ohms strapped or .5 ohms strapped.
