Gonna be mounting a 12" kappa perfect in a 1 cube sealed box, how does the infinity reference 611a sound for this? is there anything better in that price range?
Talk to mat dope or CT MIKE, they're selling PG xenon 400.1 That's a perfect match for you infinity setup and should be a good amp to any 400w rms subs, because it gives you the 1-4 ohms wiring flexibility.
