I bought 2 Visonik v4000xd amps from two guys on here, iamamp3pimp and thunder9500 with the intention of running them at 16 volts since they have been modded. I have had them for a few months and only powered them up to test them, but with the new rules changes for NSPL, i am thinking about selling them or trading them for a couple amps that put out good power at 12 volts. I can post pics later this evening, since i am at work now. PM me if you have anything to offer amp wise, or looking for 450 shipped each.
