SM5

Vehical is 08 GMC Sierra. Currently installed is a setof Boston pro 50se components in front doors, a set of Boston pro 50se components in rear doors. I have a JL10tw3 d4 down firing behind rear passenger seat in a sealed box. also have a JL w7 in a custom fiberglass sealed enclosure between driver and and passenger 1.325 cu ft of air space. As for amps I have a jl slash v2 300.4 and a Apline pdx 100.4, sub amps include a Rockford Fosgate t1000bd/cp1,
A Rockford fosgate punch 300. Head unit is a Kenwood DDX7070, I only have passive crossovers from components, my questions are would an active crossovers help? What is best way to wire for SQ, but I do like volume also? The JLw7 does has not impressed me at all, I have access to a JLw6 dvc4ohm. Would it sound better? Need help some many options, wiring is 4 gauge to amps with 1 farad cap on larger Rockford, then 8 gauge to 4 channel amps. All door skins are dynomatted along with rear can wall and sections of floor. Having all this equipment I would think I could achieve a decent sounding system. I am ok if suggestions eliminate some of it. Please could really use some expert advice. Thank you
