XXX15, 95 plymouth neon, enough power (1800rms+)

BUT, i only have approx 3.3 cubed to work with in total, which will be VERY little volume when you take out the sub and port volume

this is just an approx figure. 31 x 15 x 16. i got somehting like that to work with.

i want about 75/25 SPL/SQ and i listen to only rap and hip hop.

i need to make a box design for this.
wat are the disadvantages of this sub in such a small box?
can polyfill compensate for it?
should i jsut go sealed? :(

lets jsut pretend i didnt say the sealing thing.

anyways, what should i do?
wat should be my tuning frequency?
can someone help me design a box?

Stay ported if you want mostly spl. Go to reaudio.com and check out their box designs for your xxx and I think they also have tuning frequency's for their subs.

there are box designs, but they give the RE reccomended for SQ sealed and SQL ported alogn with tuning

i dotn have that much space to work with so i need to design one with the help of people here cuz i hardly know anyhting about box building. i can make it, but dont know jack abotu designing it.

if you cant fit the right box for the 15" XXX in your car just
dont get the 15"...

get a 12" and build the right box for it and you will probably
be a lot happier...

trust me...
