I need some dimensions for either 2 seperate boxes or 1 dual sealed enclosure for 2 10" subs. There going into a 04 STX Heritage Reg. cab. Also which has cleaner bass sound.
Thanks

 

Do you already have the subs? If so, what is the brand and model? Depending on how a driver is designed, it needs a certain amount of air space inside the enclosure. There is no generic rule for 10s, 12s, 15s, etc. I have 10s that require 1/2 cubic foot each. There are other 10s that need upwards of 1 cubic foot. You can vary that recommended volume of space a bit, but not drastically or performance will suffer. Also, if you have the subs, is the mounting depth going to be suitable for behind the seat of a regular cab?

If you do not have subs already, shop for something that will fit into your space properly, in terms of available air space in the enclosure and the depth of the enclosure. You want to retain the ability to move your seat when needed.

I personally like for each sub to have its own space and NOT share space with another driver. Dual boxes or one box divided in the middle would be great. I've seen enclosures in regular cabs range from very small simple "wedge" shaped to custom built that extend from side to side and from the floor to the window in order to get the desired air volume. Where there's a will, there's a way.

Take some measurements and make up a mock box from cardboard. Experiment with it to get it to fit exactly as desired and then you can make one with the same outside dimensions. A simple wedge box of outside dimensions of 17" wide x 17" tall with a bottom depth of 8" sloping to 5" at the top will have an internal volume of well over 1/2 cubic foot. With 3/4" MDF, the internal dimensions are 1 1/2" less than those figures. Figure 15 1/2"x 15 1/2"x 5"(the average internal depth)=1201.25 cubic inches, which is .7 cubic feet. After deducting the volume of the sub's motor structure, this would probably be ideal for a sub that needs .5-.6 cubic feet of space. The mounting depth in this example would probably be limited to 5 1/2", even if putting the sub as close to the bottom of the enclosure as possible.

 

Hey thanks for the input. I have 2 pioneer subs(I know their not the best.) and have already built a box for them that fits pretty well. It's not a wedge shape because I couldn't get the miter just right. There is no divider between subs and it is sealed. Would a divider produce better results or should I build 2 seperate boxes.
Thanks.

The key is what do the subs need as far as air space in the enclosure, and how they are being amplified. That's more crucial than having it divided into two separate chambers, I believe, although that would be preferable.

 

Well I spent most of the day building 2 new seperate boxes for my 2 10" subs and let's just say that one box with no divider(sealed) has the best sound that I have found so-far in a reg. cab environment. What a waste of time! Oh well, you live and learn. Maybe I have the wrong subs. I know the amp is strong enough and each sub needs 1 cu. ft. per sub according to the specs. I had that before with the one box for both. Any ideas? Maybe i'll go back to what I had. Any subs built just for limited air space? Thanks for the input.

 

is the suggested mounting volume supposed to be measured before the subs are in or after they are in. I too am creating my own box and want to know which way it is.
Thanks,

What size are the new boxes? Were you able to get the 1 cubic foot for each? If they are correct, there's no reason the subs shouldn't perform as well or better than in the single, undivided box. What is the volume of that box?

 

If your sub manufacturer doesn't specify, then you probably need to allow about 100 cubic inches for a typical 12" sub with a 40 oz magnet with 5 3/4" mounting depth. That's only .05 cubic feet, so it's not much of a concern. If you get into huge subs with huge motor structures, that's a different thing.

 

I have 2 10" kenwood subs that required 1.6 cubic feet of space each. I constructed one box and put necessary divides in between so that each sub had 1.6 cu. ft. of space. I then added 2 ports for each sub measureing 2" by 7". The thing is so loud its not even funny. Its powered by a 1000w Power Acoustik Amp.





Good Luck!
