Help with box for 2 lv4 15's

[YukonDCXL]

Hey guys, I am designing a box for 2 dc lv4 15's and need some help on which port would work better. This is going in a tahoe.

So far I have

48w x 17.5T x 20 D and a two common wall port 16 tall 4 wide and 14 deep... subs facing up, port facing hatch. This should tune to around 33hz

Or I was thinking of a box the same size with a Steve Meade style port 6x6x7 deep and should also tune to around 33hz

What would be the better way to go?

Thanks

Neither of them options you mention, since no one is replying to this here's a suggestion for using on about rated power, figure is just an assembly guide:
