115w x4 would be fine. Only reason I would upgrade is becuase I'm getting 97x2 right now but want a four channel so I wouldnt upgrade unless I get a few more watts. Thanks for the info.
Has anyone actualyl done power testing on the 100.4? I really want 125 watts x 4 rms but I really want a sundown amp so just curious what the 100.4 really puts out? Thanks
