I ordered the rp2000 and the amo seems to have plenty of power. I had it hook up to 2 10 inch DD at 1 ohm. Pushed them hard and never had any issues the subs took it. I received my ZVX 15 today and the unboxing was amazing. This sub looks like it can do some damage. The sub came with some defects on the dust cover, glue was on and off not tightly secured to the woofer. I wired it parallel 1 ohm. I eased into the sub let it play at a low volume for an hour or so. I decided to turn it up a bit. I've seen this sub on youtube and looks insane. I could smell the coil after a minute or so and I wasn't even pushing hard at all. I'm not sure what this will come to but I will continue the break in period for the next couple weeks. Won't make the sub work to hard. I'll leave another review in the near future and hope to give it 5 stars and a rave review. I'm really hoping this this doesn't pull a smoke show on me. I'm not over powering it and my electrical system is more than what's needed.
