box so big, trunk so small...

[immortal_sub_7]

I plan on buying 2 audiobahn immortal 10" subwoofers, handling 3000 watts peak each, and an audiobahn A2300HCT amplifier for a 19930-1997 toyota supra. the only problem is I dont know if the box will fit. audiobahn reccomends three different size boxes from 1.50-3.5 cubit foot boxes, all ported. they do not reccomend sealed. I chose to use a 2.5 foot cubit box. but, that meens it would 30"x30"x30" each sub. i thought that the best way would be to make the boxes 39"x39"x12", wich is equivilent, and stack them on top, or just make 2 and connect them together. i just want to hear some other plans that might be equivilent in size, but would fit!

Have you considered an Isobaric compound enclosure? :eek:

Not sure what that is really. i have heard of it, but have no clue what it really is.

hello, the speaker box volume formula is Volume = Length x Width x Height that will give you the volume in inches then you divide that number by 1728 to give it to you in cubic feet. So the 30" x 30" x30" box you stated would be 30x30x30=27000 then divide by 1728 giving you a 15.625ft^3 before you subtract wood thickness,speaker volume, and port volume. and a 39"x39"x12" box would be 10.56ft^3. So you can make your box much smaller.

I knew there was no way a box should be as big as I thought they would be, thanks.
