Looking to trade my basically new Infinity Kappa one for an Infinity Kappa four + or equal quality amplifier. Nothing is wrong with my kappa one. I only used it for a few days until my 1211a got fixed and now i dont need it anymore, and id like to get another amp for my highs and mids so PM me if interested! http://infinitysystems.com/car/prod...AP&ser=KAP&Language=ENG&Country=US&Region=USA
