Someone explain sub boxes?
I need a single 12in box. The manufacturer recommends .60-1.00 cu in for a box and 1-1.5 cu in for a ported box. Basically, can someone explain the benefits of each and how important the cu in thing is? Thank you

The short version is:
Cubic feet is extremely important in both applications. A non-ported box will offer a cleaner less distorted sound where a ported will offer a "louder" sound. If you decide to go ported pay close attention to your port design as this can make or break a sub box.
If you need more details let me know.

i am getting a rockford fosgate p3 12in 4ohm sub. I really would just like a non ported box because i'm not tryin to rattle peoples windows just want some good clean bass. So as long as i stay in the manufactureres specs for cu in i should be ok?

Yeah you will be great, make sure to use MDF either 3/4 or 1/2 inch nothing smaller and honestly go with the 3/4. Use sheet rock screws or long heavy duty staples like the kind used in cabinet building. Also use a joint glue before you screw or nail anything I find liquid nail works great. After it is done seal the inside again with liquid nail and you can even put some cotten in the box to help with noise. A good seal is critical if not it will make this really weird flutter sound.

#1 - you will need to be carefull to find one that will fit into the opening of your car. Doesn't matter if it sounds great in the box if you can't get it through the opening and mustangs have small openings.
#2 - be aware that those recomendations that they gave you are the required volumes that are needed AFTER you subtract the volume that the subs motor and magnet displace. There is another number on the spec sheet that will tell you the motor/magnet displacement. This number while small will need to be subtracted from the boxes displacement to get the true volume of the box.
#3 - I have been installing for almost 15 yrs and the majority of the boxes I have built were sealed in keeping with my KISS philosophy. I have never had a complaint with a properly built sealed box that could not be tweeked or tuned either through some kind of frequency manupulation(EQ) to make a completely happy customer. I have seen alot of ported(especially pre-built) boxes that make port noise or make a good woofer sound bad that led to something beind jammed into the box since it sounded better that way....
#4 - the General rule is that a smaller box is tuned for a little higher freq(kick drums, toms, ect) and will keep the sub in control better because of the airpressure created by the moving speaker in the box. It will also not need as much power and will run less chance of blowing if it is not overplayed but also will not play deep bass as well as a larger box
What ever you do make sure you mount your box to keep it in place.
