any amp will do 6 ohm, but my power is at 4 ohms. 2 ohms stereo. 6 ohms will lower my power to below the rms of the subs. i will not run my amp below the stated ohms.
I would say go with the Clarion flip out, a nice unit with the RE subs. If you are interested in the REs give me a pm I bet I can beat that ebay price.
