4 12's ported and sealed boxs

[corteznewbie]

i was given a pair of 12's in a sealed box. i alread have 2 12's ina ported box. so how bad would it sound if i had both 12's in my jeep?

Bad. You'll get cancellation. Build a single box for them all.

even if the are different rms's

even if the are different rms's

In which case pick a set and run them. All subs need to be the same and in the sane box or at least have multiple boxes with the same specs.

Well, i had the same opinion until i saw hotdog´s car, that shit looks loud as hell and no cancellation at all,of course his case is different, he has 2 12´s and 2 10´s on seperate boxes, in your case, i would try to build a single box for the subs, but it´s fun to try dumb thins sometimes hehe, i would hook up that thing and find out if there´s cancellations or if it´s louder

id be willing to bet your odds would be better running the same spec boxes but with all different chambers IMO(unless they are powered same and are the same sub)... although like they say just try it out man, you never know what might work.
