I have a 09 f150 super crew fx4...
Going to purchase the fox acoustics box for 2 -10s vented box...
I'm wanting to know best sub and amp setups you all have used with this box for 2 10s???
I was thinking maybe jl w3's, if I go with these what amp preferebly also a jl amp would work well
With these?
Thanks

 

According to JL's site the W3's like 1.25cf ported tuned to 32hz. So two of them at 2.5cf after displacement. The fox box has 2.05cf before displacement and tuning is at 36hz. So the airspace might not be enough for those subs to perform very good. And the tuning being higher doesn't help too much either.

You need to find a sub that needs right around 1cf ported.

 

I don't know of any 10 that use a port with that little of airspace. that gives each 10
1 cubic foot I would seal the port and find some subs that will fit in depth. Most 10's sealed are between .8 and 1.0 cubic feet of air space. Don't for get that with 2.05 cf you still have to minus the speaker displacement. which would put you pretty close to the .8 cf mark.
