Hey everyone I am new in the car audio world. I have had a cheap sub setup and have finally taken the first steps to upgrade. I purchased a JL 12w6v2 for $180 this weekend and am ready to build a box for it. I would like sealed and the JL website says 1.25^3. Is this the best size for SQ? Also is it better to build a square box or a box with curves (wedge look)? What about polyfill? I am still new at car audio so any tips are greatly appreciated!

build it to JL's specs, and fill it about 1/2 way with polyfill

I also recommend building it to JL specs. The only thing I might suggest is going with a ported design. I previously had 3 12W6v2's and they sounded just as good ported, only LOUDER! and a lil LOWER!

Feed it a clean signal and it'll take over rated power and sound great doing it. The W6v2's are a nice sub.

i wouldn't add polyfill if the box is built to the right specs inless you do ported u can put some chicken wire infront of the port if a little polyfill infront of it to get rid of some port noise.

hahaha, this should be good, lol.

it works like this: The polyfill fools the woofer into thinking that it's in a larger box (one with more air, or internal volume, in it). than it really is.

so biulding a jl spec box then stuffing it. is pointless.(because it's no longer built to spec)

polyfill stuffing is a alternative for people who can't or don't want to allot a lot of space for a subwoofer box.

lol, gotta admit Mike, he knows his polyfill... lol, I still wouldn't chicken wire it near the port though.... If you choose to go sealed... (and this is totally from experience) if your running close to or over rated power sealed, go 1 cuft and fill 1/4-1/2 way with polyfill.

If you go ported, 1.25-1.5 @ 34-36hz is perfect depending on power. They'll dig down to 28-30hz no prob. They were some of the best subs I've ever owned.
