Assuming that your L7 12s are the Dual 4 Ohm version and you could drop the sub channel to a 1 Ohm load.....and further assuming it's under-rated by a factor of 25% giving 1,000w @ 1 Ohm for the sake of argument....
That would feed 500w to each 12" L7.
Will that work?
Yep.
Will it make those Solobarics give all that they can give?
No.
The L7 12 can take more than just a little bit above 500w worth of clean signal all day long. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
But as far as just looking at the amp for the same of amps?
Yes, it's a durn nice unit. //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif
