Hey I have 2 12w6v2's in a sealed jl box powered by a PPI PCX 2200 amplifier thats rated 400x2 rms at 2 ohms. Sounds good in the trunk of my car for now. BUT NOW what i wanna do is start over and use my 2 JL 500/1 amps and upgrade to 2 JL10W7's. What do you all think about the differance in SQ and SPL that ill be getting in the new setup? and what kinda box should put the 10w7's in? What do you all reccomend for my JL setup. Thanks
