If my sub says it needs a certain box size, how important is it that it be exactly that size. Also, I've seen boxes made out of different thicknesses, is thicker better?

The size of the enclosure is very important. Especially if your using a ported/vented enclosure. As far as the thickness goes don’t use anything less than 5/8 but I would recommend 3/4. But the thickness also depends upon the size and application of the enclosure. You can read more on the importance of the proper size enclosure here https://www.the12volt.com/caraudio/boxes.asp

So, I have a sub that the recommended size is 1.00.  I am buying a cheap box off of ebay untill I save up for a custom made box.  There are two boxes on ebay that I am looking at...one is 3/4 but is 1.25...the other is 5/8 and is 1.00.  Would I be better to by the 3/4 at 1.25 or the 5/8 1.00?

Either one will work. But if it’s a temp box I would go with the 5/8. If it’s a sealed enclosure which it sounds like it is not as sensitive when it comes to volume. You could go with 1.25 but I would not go any larger than that.

It is a sealed box.  which is more important, the size or the thickness?

In my Experience with Audiobahn woofers 1.0 sounds the best. When using a sealed enclosure the volume can be +or- the recommended volume a little bit. In an enclosure that small there will not be any benefit to 3/4 over 5/8 so I would suggest the 1.0 / 5/8

Hey bberman, im kinda curious why you dont recommend that box. I see why he chooses it, its what Rockford recommends which most people would go by. The box seems small to me but i've always had ported boxes so im used to seeing the bigger volumes. Anyways, was just curious for the sake of all newcomers who would normally go by what the manufacturer recommends.

something to think about i would go with the 3/4 1.25 box only because of the speaker displacement . that would bring the volume down pretty close to 1.00 just something to think about.

amador is right, you have to take the displacement of the speaker into consideraton.  you could look up the displacment of the speaker, but I would just go with the 1.25 box.  After subtracting the disp. of the speaker it should be right around 1.0 cu. ft.

Either enclosure would work for him. He probably would not be able to hear a difference between the two volumes. As far as the displacement of the sub goes in fosgates calculations they figure it in to that 1.0 cu/ft.

I would personally prefer the 1.25 cubic foot enclosure and 3/4". I have built numerous enlcosures for shops that I have worked at, and I like the ridigity of 3/4" MDF, not that an audible difference can be heard, but just the fact of knowing that it is stronger. Along with the fact that using an enclosure where the volume is a little larger is going to allow the driver to drop to lower frequences with better tonal balance. The speaker will be able to play lower frequences better with the larger volume. I do not suggest that you go to extremes with this idea. A 4.0 cubic foot box with that speaker is going to sound like garbage.

Just thought I would add my 2 cents.

Ok...now I have found a 3/4 1.06 box on ebay.  Is this the best choice?

I like factory built boxes. they save a lot of time and money just look for 3/4" board and glued and stapled. and glued and screwed termanal cups
