May 27, 200817 yr it's best to just choose what subs you want then find the amp that works best for them.If you are trying to compare different effects of ohm load on the same amp, then this will apply-Damping factor decreases everytime you half the ohm load.THD distortion jumps usually by a multiple of 10 when you half the ohm load.Power draw and output on average may double when you half the ohm load.The lower you drop the ohm load, the more current the amp will output through the speaker wire...So if you are doing a big install, using small wire might melt it, but you gotta be doin some pretty hefty power.
