SPL2K

no...single layer is fine. Just use a peice of 2X4 from the baffle to the back of the box in the center.

I could do a 154 with 2 comp 12's..... .....in a crx.

im trying but i also want to be there for Desert Storm. I dont know if i'll make both.

if thats the case then you will be safe tuning a little bit lower. (i would say 38-39) but expect to lose 75% of low bass once you "drop the top".

wait...... how much time is spent with the top up / down?

40-41

thats great but most companies wont hand out amps / subs / batts / video / etc for free to just anyone without seeing what they are capable of with their product.

what kind of music do you listen to mostly?

thats incorrect.

Win a couple of world championships out of your own pocket first. Then the sponsorships will come.

Lose the chrome gas door. 24" red color matched wheels with a polished lip. 4 12's or 3 15's in a nice red fiberglass box below the window line.

you can get it loud but you have to tune higher.

did your brother have a convertible also? Its impossible to get decent low bass in a convertible.

You better tune it to ATLEAST 40 or you wont even know its back there with the top down.

definately box 1

using your dimensions... 35.75W X 11T X 25D you've got 4.42 cu.ft. Build the box that size with the 4 8's along the front of the box with a slot port along the bottom right below them. The vent should be 34.25W X 1.25T X 18L. That will tune around 37. Divide the center of the vent with a strip of 3/4 for a brace.

agreed! .....but i would tune it around 40 or 41 so port length doesnt eat up too much airspace and because they are 8's.

the 2 cvr's would be louder but if you are wanting 2 15's, then why not just get another DD 3515?

Did you build it yet?

Not if you want SPL.

Nothing in the corners, no resin, and no bracing unless you are using more than 2000 watts. Maybe 1 2X4 from front to back between the 2 subs.

yes....to all your questions. Subs dont have to be touching but you want as much room as possible between them and the port.

49W X 17T X 20D port is 15.5T X 5.50W X 13.75L Subs rear firing as far to driver side as possible and port rear firing on pass side.

thats no where near an "SPL" box. The bracing alone is costing it 3db. Then there is the port and port placement.

lol...overpriced prefab / non-custom POS.
