Midbass woofer module

[gtpsuper24]

I've have 2 Profile California 12" car audio subs. I liked to build a midbass out of one of them. I decided to go with a sealed box Profile recommends a 1.25cu ft box. So would this mix well with my SVS 25-31pci? The profile would go in the left front corner by the left front speaker and center about midway. Its only going to be in the 50-100hrz range.

(Fs) 25
(Qts) .48
(Qms) 4.17
(Qes) 0.54
(Vas) 4.84
(Xmax) .34
(Re) 3.6
(W) 500
(Le) 2.3
Would like any suggestions on if this would be a good idea, what amp would anyone recommend, and if I could or need to use something like the BFD as and eq to help get it to blend with the SVS and the mains.

Profile recommends a 1.25cu ft box

That would be a car audio recommendation where the extreme amount of cabin gain is taken into account. Have you tried modeling the sub in WinISD?

What model number are the profile subs you have, when I punched the specs you gave into BassBox Pro, they didn't seem to work out right. Or, do you have a link to the owners manual?

No I don't have a model number they're about 5-6 years old. Still brand new just have been sitting in the box. The only thing in the manual is the product specs I listed and how to calculate enclosure for 1.25 sealed or 2.0 ported thats it. I check out the website but they are not listed anymore. I tried winisd but doesn't to me any good cause I don't know what i'm looking at or for.

1.25 sealed or 2.0 ported is a car audio recommendation where the extreme effect of cabin gain is taken into account. Each sub models to 4 cu.ft sealed for a Q of .7. and will handle 150 watts with a Hi-Pass filter at 30 hz.

This is what I came up with. A bandpass enlosure that would need a highpass filter around 35hz. I think one would provide plenty of punch if the specs are right.
