Okay so u know I want fiberglass boxes. But until I get the chance to actually work with fiberglass(summer) and be good with it, I wanna try and make enclosures like I'm going to fiberglass but with just mdf for now n carpet.
I just don't know how much airspace my subs need. They aren't new or anything, 2 years old, and I bought them as a package that came with the amp and enclosure. I have info on the amp but not the subs that I know of. Is there some ratio or something for like.. rms and airspace? Or how would I figure this up?

I don't know of a ratio or formula but I've never had a need to look for one.
What size is the enclosure that the package deal came with? You could figure out the airspace of that enclosure.

^^^ I'm working on deadening my hatch area which will come in time as I bother to get some dynamat but for now I mainly am just wanting my subs on the sides out of the way instead of sitting right in the middle of my trunk. Cause it kinda defeats the purpose of having reclining/fold down backseats lol. If I had it more of a show setup then I'd leave it and do a nice big custom enclosure but eh lol.
As far as the stock box goes.. I can measure it, but it's ported as well inside. So I'd say I'd have to take the subs out to measure the inside. Mainly just how its ported is getting me. I mean I like the sound of ported, but if they are seperated into 2 seperate boxes, would porting them be worth it? Or what..

you know what im thinking you could do besides some trigonometry ha
just port the subs enclosure, with the subs in place
turn your music on and just listen
widen the hole until you get that bump your looking for

that's a lot of work dude, and a lot of hit and miss
first off, just google your make/model of your subs and try to find box specs (it might even be on the company's website if they're still produced) then look for a box calculator somewhere on the internet, I know RE audio has one, there's lots of them out there though.
anyway, you'll take your speaker parameters, desired tuning frequency, and box size and plug them in the calculator, and they'll tell you what size to make your box and port

Yeah I know of the RE audio calculator for ported boxes, and another one for sealed or ported. I'm gonna find my manual to my amp or w/e and see if I cant find out which model the subs are today.
