What amp do you have? One with a SSF? RE says 2 cubes sealed and 4 cubes ported to 30. You might wanna try looking for fellow SE people...

If you get the 1200.1, you'll need to get some FMODs....what's your price range for the amp?

As far as box size....try around 5 cuft after all displacement

I'm a fan of the Hifonics BX1500....great amp and can give each sub 750 RMS.....My 12" SE's take it like beauty's.....

Hey, Jmac I am going to get 2 15 inch se's my for my van and basically what I am looking for is 4.0cuft tuned to 30hz. Can you give me a design also?

The measurements for my trunk is width 45" x height 18" x depth 14". I don't want to remove the back seat so the depth can only be 14". I am looking for a slot port too and a common chamber.

Jmac, you really need to open a Paypal account and charge people like 3 or 4 bucks for box calculations.

Thanks Jmac. However doesn't a upward port with the subs facing the back of the car cause cancellation. I always thought that if the port and sub are on different sides cancellation occurs. I going to remeasure my trunk and see what I can do (maybe move rear seat up forward).

Should be fine...

Ok, I did some measuring outside and now I have better measurements. I moved my seat forward and I have measurements of 17" deep x 17" high x 46" wide. I had to lower the height since my seat slant back a little bit. That should be enough to put the port on the same side as the woofers. I want everything on the same side since I like to put a blanket over the top of the box since if makes it real easy to see the box from the window. Do you think that should work?

Wow Jmac, I am impressed. That box is perfect :thumbs_up .I didn't expect you to design me a second box. Your a real nice guy. You even made it to the original measurements. Thanks again. Do you have a program that does that or did you do it in paper?

Wow. thanks again.

I think I can afford 17" x 17" x 46" at most. I am going to see if I can can design a box that could work.

hey i was just thinking. am i gonna need to make any type of braces or anything in my box for my subs?? maybe a double thick front panel?? each of my subs weighs about 20 lbs. i was just wondering

I would puta brace right inbetween the 2 subs from front to back. They don't take up too much space and I think it worth it to be safer then sorry. Especially since you have an internal depth of 16.75. I decided to go with an XXX and I added in a brace from front to back couple inches from the woofer to prevent flexing.

ok so since bracing is good. here is the question, how should i brace it?

FalconXtreme

another question i just thought about, should i use screws to secure my port and braces or just glue? thanks

Also, if you wanted to use just glue, it'd be a good idea to use biscuits.
