Sell off the 10s, get (1) 12W7 and (1) good class D or high current amp. You'll have all the sound you need coming from one properly powered and enclosed 12W7.
Boss, Vibe, Lanzar, Coustic, et al is proven junk. Not worth the scrap parts they are made out of.
Shop around, you can find excellent deals right now on good quality class D amps from MA Audio, AudioBahn, HiFonics, etc. that will do an excellent job moving that W7.
I've got (1) 10" MA Audio XL competition series sub [freakin thing weighs almost 26 lbs.] and a HiFonics XI-Zeus pushing it and while it might not be a db record holder, you can't hardly sit near the car with it cranked anyway. Have less than $500 invested in the amp and sub. What else do you need in a daily driver anyway???
Your JLs require a ton of amp power and you're better off with one less sub than trying to push them with junk amps.
