I have a lanzar opti2000d amp on order from lanzar, it was an offer i could not pass up @ $300. Never heard this amp perform. Anyone have any experiance with it? I will be using it to drive subs currently 2 Kicker CVR 10's in sealed boxes. These speakers will be replace with another sub I'm thinking one IDmax12V3D2 and hit it at 1000 RMS. I have heard good things on this sub.
