Old-School 15" MTX ThunderPro 750 Question

I have a question some of the old-school guys might be able to help out with. A friend of mine has no bass in his 98 Explorer right now. He wants something, but is on a very tight budget. I have had a new pair of old-school 15" MTX ThunderPro 750 watt subs tucked away in my laundry room. The ones with the red rubber surround. Don't ask me how I obtained them. LOL. I offered them up, and of course he accepted. My problem is, even though they are new and still taped up in their original boxes, there was no paperwork/specs with them. Does anyone know anything about these subs? Do they like a sealed or ported enclosure? How much box volume do they need? Etc. Just trying to help my buddy get some bass in his ride, and since I will be the one assembling the box, I need all the help I can get. Thanks in advance for any answers.

Is it the MTX ThunderPro TP1540? I scoured the internet and all I found was pictures of it...although it did show up in WinISD as a sub that had previously been saved. If you go by those numbers, for the pair it suggests 5.844 cubic feet and two 4" ports 9" long for a tuning of about 31hz. Other than that, all I can suggest is to contact MTX and ask them.

Didn't have much time to mess with it, since it was kinda late at night, but it does wreak a little havoc on the sunroof. LOL. Hope to play around with it some more this weekend. Still need to get the 4-channel amp installed for the mids/highs.

Any luck with 4 channel amp install ?
