I have 2 12" subs laying around that haven't been used in a while and I wanted to build a quick box for them. I usually find box ideas on this website or other forums for whatever subs I have but these are a no-name sub so I have no idea what kind of box to build for them. They have always been in a simple ported box, 3.5 cu ft tuned to 35hz, but this box doesn't fit in my 02 Grand Prix. At first I was going to just build a box to that size/tune but make give it a smaller height so it will fit but I decided to maybe try something new depending on what kind of ideas I get from you guys. I will post the specs to the sub below, but I want to figure out if maybe it will sound
in a different size box, tuned different, or even in a 4th/6th order bandpass. I know bandpass boxes are hard to build but I did one for my SA-8V2 and I love it. I know the box has to be built right and made for the sub so if anybody knows if with these specs if it would sound good that would be awesome. Any ideas are greatly appreciated. I was also thinking about porting through my rear deck or my ski hole in my rear seat. I've tried some calculators but get some crazy numbers like 104 cu ft for ported.
