Hello,

I REALLY need help in the box design area

- I have 2 Type X Alpine 12" Subs ( http://www.alpine-usa.com/en/products/product.php?model=SWX-1242D&lang=en&tab=F )

- The maximum box size I can put in the car is 37x14x11

I dont know if Sealed/Vented/Bandpass would be best considering the overall box size or what it should be 'tuned' to

Any suggestions???

Thanks so much! ~Emerald

Sealed will let you run the smallest box size. It will lower your output by 3db or so but it depends what type of system you are going for. Think if you want to sacrifice spl for box size. Those two 12s will still pound in a sealed box. In fact the type X are better designed to run sealed. So if you have a big load of power to give them I would go sealed. If you have a weaker amp I would still go ported. Go to the alpine's website and download the manual for them, they give dimentions and stuff for the boxes.

I was going to get a type-x but after reading reviews it seamed like everyone was going sealed with them because of their design. I had the room and wanted to go ported to get the most spl so I didnt get them. But if you want to go sealed to save room then you have great subs for that.

Thank you!

Im running a single Clif Design CDX-20A. Should I go bigger for the 2 subs?

Go bigger as in with a bigger amp?? That amp should be all youll ever need.

great!! I'd have to put a second one (if needed) in the back seat!

Im gonna finish up the box tonight.
