box design for 2 12" Mmats juggernauts

[TheFreezy98]

I need some help with the box design for 2 older 12" Mmats juggernauts. I was told by Mmats that 1 juggernaut needed 4.5 cubic feet with a 50 square inch port by 18". this seems very large for 1 12". they also told me that the t/s specs are no longer available. they need to fit into a trunk of a 90 ls400.

• Fs (Hz.) 42
• Vas (Liters) 27.6
• Qts .45
• SPL (1W/1M) 88db
