Those dimensions are more like 9.3 cubes and that's not counting all of the displacements.....

Shiiiiit this isnt good news......i need to figure out a way to get these in here.....

A sawzall and hammer come to mind!!!!!!!!..........lol

 

[xxlmagnum 10+ year member]

so question then....single 18 or two 12's???

 

[bumppinKota]

if you change your height to 27... if thats possible... that will put you at 11 cubes if my math is right

There is a local guy here with a single 18" DC Audio level 4 and about 3k doing a 153...........In a Magnum.......of course his box is tuned at 45hz.............I would do the two 12s if your plans are to listen to music decently......

All i need is 4-4.25 cubes per 9515....so like 8-8.5cu ft NET for these still not sure how my dimensions wont work

 

[double 07 10+ year member]

because a decent sized port is going to take up 1.5 cubes of the space you have to work with unless you want to tune it to 50hz.........I just played with the numbers....with 35 hz tune and decent amount of port area you are netting about 7 cubes........you might use aeros and get a little more....

 

[bumppinKota]

i thought your original specs were good. just you said you were looking at 11 cubes... lol i just changed one number to get you at 11 cubes. i think your on the right track... but thats just me.

 

[bumppinKota]

oh i forgot to calculate the port...

 

[double 07 10+ year member]

21" x 40" x 23" with 3/4" wood will NOT net 11 cubes on any calculator.......sorry

 

[bumppinKota]

21x40x27 will

He probably can't do over 23" if he plans on the hatch closing.........lol

 

[xxlmagnum 10+ year member]

yeah dude kinda want my hatch to close...and no way i can place my m3a's underneath the false floor they would go up in flames real quick....**** im stuck
