orion cobalt co600.4 or infinity ref475a?

im unsure on which amp to get: ORION COBALT CO600.4 or Infintiy REF475A im planning to power a pair of 6022i's and SPS-69C's. which amp would you pick and why? thank you.

the issues that come to mind for me is the fact that speakers are far apart in power/sensitivity. 3db will make speakers 2x more sensitive ect. gain levels can help adjust, but is just less headache to match speakers by power and output level close as possible. neither amp will help if going for max volume due to 4 ohm max bridging or you could help the alpines output by giving more power to overcome the spl rating issue the 6022i's are already at 2ohm while the spr's will act weaker in contrast if wired the same way ser/par not a huge issue but make sure you know how you will wire to compensate 2/4/ohm difference first. good luckskills can go to the grave or can help others to get in on the action that big buissness gets richer off of every day. good luck to all the ones trying to climb to the top.
