Hi, im new to making a sub box. I checked out a tutorial on youtube and I have read the instructions on crutchfield as well. I have two 12" alpine type r subs. The manual says that the dimensions should be 13x13x12.5. I need to know if this is just for one sub or for both. I also have used this website http://www.bcae1.com/spboxnew2.htm to help with the sides. But i need to know the dimensions for two subs sealed. I measured my trunk and the height can be no more than 15", width no more than 38", and i dont want a depth of anything bigger than 15". Any feedback would be appreciated. Sorry for the long post.
what do u mean by doubling the dimensions. should i double the width only? I want to make the box for two type r's. I only know the dimensions for one. It would be helpful if u could enlighten me a little more.
Sorry, I should have been more specific. If what you posted was the ouside dimensions then your new dimensions should be 26 wide by 13 tall by 12.5 deep.
Have you considered a ported box? According to your first post you have more room in your vehicle. You could build a box with the outside dimensions 36-inches wide by 13-1/2-inches tall by 14-inches deep. The port would be 12-inches tall by 2-inches wide. It will need to be 11-inches long. For a ported box follow these directions http://www.caraudiotalk.com/audio-forum/showthread.php?t=7031
