subs for durango

You may need to look into very small 10" subs, and they have to perform whell in small enclosures.  Im shure you could fit 1 Adire Brahma 10" and that should be whell enough.

Take some measurements and post them meybe.

Do you need all the seating in your Durango? do you have a third row seat? Have you seen this: https://www.the12volt.com/installbay/forum_posts.asp?tid=39376&get=last

The stealth box aside, you do not need two subs to get very good bottom end.  I have 1 10w3 in my suburban and it is more then adequate.  While we all have a subjective view of how much is enough, no one has every listened to my system and said it needed more bass.  The comments i often get are "balanced" and "smooth".  That one 10 can give a good whack in the chest  and make sh*t in that little cup holder on the dash vibrate all around.   It sounded louder in my wife’s 00' Subaru Legacy, but the cabin in the legacy is about 1/3 the size of the suburban.  If I ever upgraded it would be to a 12", probably a 12w3 v2, alpine type S or Infinity Kappa perfect.  The quality of your subwoofer has allot to do with the output and the quality of bass.

If I was in your situation I would look into getting one 12 and be prepared to feed it near the recommended RMS power rating to milk it for everything you can get.

Ok, there is this:  http://www.cardomain.com/item/MTXDD8T45  Im just not a fan of MTX's low end stuff and I would not personally choose 1 8".

I would have to agree with boxmaker here...the JLW6 is a good driver and efficient and will perform well in a small sealed box.

Lookin at getting two myself (10w6)  might upgrade to the w7 depends on the financial situation

Power Acoustik states it's FUBR 10" only requires .5 cubic ft of vol. for a sealed enclosure.  Could I reduce that if I use Polyfill?  Thanks to all for the input.  As for the 3rd row seat, yes I need it.  I have 4 children.  OUCH!!
