Wonderin whats.better for 4 12 sa's d4.They will be going in a 99 crownvic.thank u in advance

Do you have room for four 12's ported? What are your goals? Did you already buy them? I do not like the SA sealed.

the word "better" will change from every person. If you can fit the ported option, I would do that.

I have two on the way.gotta save up to get the other 2,should be a month or so.I should have the.room i have a big trunk.

I highly doubt that you have enough room to do it right unless you build it in your trunk. (even then you might not have enough room) Sometimes less is more.

That sucks but it is possible.i might stick with the two i have and build around that.

Well, go take measurements. Seems to me the easiest thing to do. I would then simply wait to build a new box for the four 12s. No sense in using a box for less than 30 days.

I agree with what has already been said, If you can manage to have them ported, do it.
