if its 2ohm go with dual 4ohm sub's

that'll push them, but not to their full potential.

you'll have to get the dual 4 ohm versions. wire the coils together in series, then the subs together in parallel for a 4 ohm final load. bridge the amp for the 880 watts.

that'll power one nicely, but it'll underpower two.

the amp specs are:

370 watts RMS x 2 at 4 ohms (440 watts RMS x 2 at 2 ohms)
880 watts RMS x 1 in bridged mode (4-ohm stable in bridged mode)

for future reference, never look at the peak numbers like you did when you said it 1920 watts. thats the peak. you always want to look at the RMS numbers.

the solobaric L7 has an rms rating of 750 per woofer meaning you need an amp that puts out around 1500 watts @ 2 or 4 ohms depending on the subs you get.

if you hooked those sub to that amp it you would be underpower the subs major and most likely that PA amp would go into protection from being too hot.

if i were you wanting to get those subs this is what i would get:

AMP =

Subs =

(2) 12 inch L7's - dual voice coil 4 ohm subs

and then wire it to 1 ohm and the subs will be getting around the recommended watts.
