So i have hadthese crystal subs laying around for a while and was considering porting it in the back of my Accord. I found the box calculator on REs website quite helpful and when it comes to ported enclosures im clueless. but here is what i have. Roughly 6 cubes @ 32. I was wondering how this would sound. I'm looking for loud with some sq.

Here are the dimensions of the box that i got from the RE website:

box width = 35
box height = 30
box top depth = 15
box bottom depth = 15
wood thickness = 0.75
square port height = 28.5
square port width = 3
square port length 1 = 11.25
square port length 2 = 12
total port length = 28.5
box volume (ft3) = 6.039
tuned frq = 32.487

and here is the only information on the drivers i could find. These are Crystal PROst subs SVC 4 ohm. I will be running these to my RE 12.1

12 Cast Aluminum Basket
4 Layer Voice Coil
Butyl Rubber Surround
Woven In-Spider Tinsel Leads
Bumped & Vented Back Plate
5-Way Binding Posts
Fs 22.252 Hz
Re 3.6 Ohms
SPL 86.95 1watt / 1M
Qms 4.185
Qes 0.319
Qts 0.297
Vas (Sd) 63.952 Liters
Bl 21.845 Telsa-M
Power Handling 300w rms
Recommended Enclosure: 1.2 cu. ft. sealed
Mounting Depth 5.25 in.

Any suggestions are greatly appreciated. I really need some input on this and i am really unsure on if the box will be big enough to go ported with these subs. If i definetely need a bigger box than i might as well stay sealed because the dimensions of the box is the maximum area i have to work with to fit in my trunk.

Is there a minimum enclosure size or general rule when applying ports to a certain number of subs? Would 6 Ft^3 cut it or would i need somethign a lot larger. I never really understood how that affected the kind fo soudn that came out.

I have not had any luck finding this kind of information, can someone give me an idea of what to search for maybe im just not searchign the right things.

thanks for the bump man. I think after much consideration and also the input of others i have decided to go with 6 cubes sealed. shared chamber with double baffle.
