My recommendations for my sealed box is 1.00/2.00 but the one I got was 1.3/1.3. I have a single cab though, how will this effect it?

 

I am assuming the the first number is minimum and the second would be maximum. So the box you got at 1.3 should be perfectly fine. Honestly, Sealed boxes are much more forgiving on the box dimensions compared to vented boxes where differences in volume can make a big difference on sound. YOu will be fine. You can also put some Polyester Fiberfill inside the box as well, this will make the box seam a little larger as well because of the way it deflects reflections.

 

First is minimum with greater power handling and right is for optimum air space with less power handling. Do I have to put polyester inside?

 

No you do not have to put it in there. I just suggested it.

 

Someone told me if the dim. are not correct it would harm the subs, is this true? And poly. would make it sound better?

 

Like I said in the first reply, sealed boxes do not have to be exact. You will not harm the woofer with the box being not exactly perfect. In a vented enclosure, it is much more important.

As far as sound, different sizes will make the woofer sound a little different, but as long as you are close you willnot notice any difference. If the woofer you have calls for between 1 and 2 cu ft, then your box of 1.3 is just fine for your application.

What woofer do you have and what kind of box did you get anyway?

 

(I have a reg cab)2 SVC 10" Memphis PR in a sealed. I some more questions though, would it be a good idea to put tweeters in w/ factory system? And or caps nessicary?

 

Caps are useless and tweeters can help, but a proper component set up front would be the best solution.
