Im looking to build a custom box for my SRX, I just cant decide on sealed or ported. Anybody have experience with this problem.

As far as I know, it depends on what kind of music you listen to. Sealed has to have an exact air space inside the box and gives a crisper sounding bass, where as ported are easier to build and are better for bellowing bass like rap or hip hop.

You're mostly right! It definitely depends on what kind of music you listen to, and what the goals are. Sealed boxes do have a tighter/crisper sound, but from my experience are actually easier to build, since you don't have to worry as much about getting the port juuuuust right. The biggest thing you have to worry about with a sealed box is making sure it's sized appropriately for the sub you intend to use. Upsides to the sealed are the ease of construction, tight/clean bass, and typically smaller box size. A properly built/sized/tuned ported box will usually put out more sound with the same wattage (at least down to the point where it's tuned to roll off), but is more complicated to build and you may sacrifice some accuracy and you really reduce the sound below the frequency the box is tuned.

Personally, I prefer the sound of a sealed box (or maybe I haven't heard enough perfectly built ported boxes), and that's the route I typically go. They're easier to accommodate in weird places. In my last car, I built a box for a 10" sub that fit just behind the right rear tire in some unused space in the trunk. (see here: http://carphotos.cardomain.com/ride_images/3/1723/1109/29305554043_large.jpg) It wasn't super loud, but it added the little bit of bass that was lacking. So far, I'm resisting the urge to do anything in the SRX. What kind of sound are you looking for? What's the budget? Do you have a particular sub/amp combination in mind?

There is a TON of information out there...
