1967 Gto car audio subwoofer set up

[keith4909]

I’m currently setting up my stereo. Getting closer after like a two year break from third child.
Running
(2)jl audio 12w6v2/v3
xd1000.5 amp 1000w



How should I set this car up for super high end bass.
How would I run the box, sealed or ported?
Should I run one box or two? And where in the trunk?
I would love to put facing out under package tray and rear seat but not sure if there is enough space and volume because of the rear differential hump in sheet metal.
Where to put front speakers. I tried the speaker kickpanels but they don’t fit and the speakers are cheap. Should I put them in door?
