Alpine MRV-F450 5 channel 2 0hm stable

[RajunCajun]

I'm running 3-8 ohm w1 12s which gives 2.67 ohm load can the 5th channel handle this ohm load? Also I have a 4 channel Alpine MRV-F540.

If the F450 is not stable at 2.67 ohms can I bridge one channel on the F540 to power 1 sub and power the other 2 with the F450? or would this cause a sound problem?

Or would it be better to run all 3 off the F540 which is 2 ohm stable?

The manual says 200 at 4 ohms but I can not find anything about the 5th channel being 2 ohm stable. I finding conflicting reports online about being stable. So with that lets say it is not. Would it be ok to run 2 8 ohm subs on one amp and 1 4 ohm sub on the other or does that cause a sound problem? each sub has its on chamber in the box

Maybe I'll get a bite on this one. Can I run 2 8 ohm subs on the F450 200 watts at 4 ohms ( 100/sub) and 1 4 ohm on a bridge channel of the F450 at 100 watts?
