Two 12 inch Pioneer Shallow Subs

[allvent]

I need help for specs on building a custom sealed enclosure for 2 12" shallow Pioneer subs.. it will be in a mitsubishi lancer but i need my trunk space so thats why i went with the shallows.. most boxes i have seen are just for one and feeling a little lost and would like the best sound for the two.. any ideas or pictures with specs out there? Seems there arent too many ppl out there with knowledge on the shallows..

Any help would be appreciated..

what dimensions do you have to work with?

you can build a small sealed box thats about 14" tall, 8" deep, 26" wide... thats about all they need.

I have about 18" tall, 12" deep, 36" wide

I am really new to all this and am having it built.. pioneer specs dont really help me with the two. so have resorted to searching forums..

another question i have is should it have polyfibre fill and should the two subs be divided in the box?

using poly fill is a good idea, you can build a slightly smaller box and using the fill, the subs will act like they are in a larger box. deviding the air space is good also but thats up to you. if one sub fails in its own air space, it wont affect or damage the other but if they share the same space this can happen but usually dosent.
