What are the max dimensions of your space? What kind of music do you listen to?

Thanks Triticum, the max space is 36" w x 17.25" d x 15.75" h and I like to listen hip hop, country, reggae, decaf, dj snt...

I have built a few boxes tuned between 33-40hz for this vehicle and have been happy with the response. The suspension on these subs is stiff so I am not too worried about playing under tuning. I have one of the 12's right now in a box that is 2.75 cubes after displacement tuned to 34hz on 1k and it has not bottomed out and it still hits the lows pretty well. I think a pair in the right box will hit pretty well.

You don't have enough space for a 4 net box on those dimensions, you may want to see if you can get some extra space.

Does it have to be 4 cubes? I have no idea what's recommend for this sub. Manual only gives sealed recommended specs at .9
