My current setup:
Profile Clarius 600 powering a pair of Infinity Kappa 6x9's 3way

Profile CA200 powering a pair of RF 3-way 6x9s FRC3369


I would like your opinions on which kicker 4 channel amp would match these 4 6x9's. I mean they sound decent right now, but I think a better quality amp would increase the sound quality and power.
I plan on buying it off ebay from one of the wholesalers. i know no warranty. but heck, i could buy two on ebay for the price of one on crutchfield.

I bought a infinity basslink, which i really enjoy. plays nice deep bass. But i want my 6x9's to supply some decent midbass.

Thanks for any help.
