1. you need to stop posting the pics of charts......

haaaaahahaa

2. you can hook each sub to a channel... you'll only be 25watts lower then the rms of the sub that way.

on the other hand ou could parellel the subs and bridge them @ 2 ohms... the amp looks like it should handle itthen you'll have a mono at 150watts rms per sub

3. Power Ac... isn'nt a bad amp... but your paying for more channels when all you need is a mono SUB amp...... as we've suggested before the jbl 300.1 is excellent!... i think they have them at IKESOUND.com real cheap.

do not bridge that amp and put a 2-ohm driver load on it.
you'll fry the amp as it'll see 1 ohm.

Why don't you series the subs then bridge them on the amp then the amp will see a 2ohm load.
