Type R Box Question

[Buddacris77 10+ year member]

Ok I have 2 Alpine type r 12"s and Im about to build the box. It will be ported, but I want to be sure the specs I am using will give me the sound I want. For referance I drive a 2001 Durango. I want SPL and I want them to be able to hit the lower deeper notes. Here is the specs on the sub........

500Watt RMS

Vas 45L (1.6ft^3)

Qms 7.89

Qes 0.50

Qts 0.47

xmax 18.2mm

Fs 29Hz

Frequency Response 25 - 500Hz

First I am making the box two seperate chambers.... at 2.2Cuft @ 36Hz Now before I cut the wood someone please either confirm that this will sound good or give me some better advice. Thank You

Hitting the lows and spl don't always mix. However, I do hear that Durango's peak low.
