I have an a/d/s/ PQ10 that puts out 37.5RMS*4 which I currently use it for two channels bridged and gives me 90*2RMS at 4ohms.  Someone suggested to use this amp to run my 2 sets of 6.5 components.  I have 1set of Diamond M661 rated at 20-170 and a set of Focal 165K2 rated at 100 to 200.  How can I wire the amp to give me 4 channel stereo at 2ohms?  And, would it be enough power for the 2 sets of 6.5s?  Also, would it run too hot if I do this?  Or should I leave it at 2 channels 90*2RMS for the Diamonds and my Kicker 705 which puts 400RMS for my subs and 160*2 RMS for the Focals?

I'd really appreciate if someone can give me advise on this cause I'm pulling my hair thinking on what would work best.

I'd leave your setup the same way it is now.

If you wired the front and rear left speakers to 1 channel, and the front and rear right speakers to another channel (leaving the 3rd and 4th channels unused), you would would get 2ohms stereo. But you would lose fade control and would only be getting about 45-50 watts per channel (apx 50x4@2ohms based on the specs you already provided of 37.5x4@4ohms and 90x2@4ohms bridged). That means each speaker would only be getting apx 25 watts. You're better off staying with the way you have it now
