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? How much box volume do they need? Do they like a sealed or ported enclosure? Etc. Just trying to help my buddy get some bass in his ride. Thanks in advance for any help.
I have a ThunderPro 8 DVC that I picked up years ago. Thing is a great workhorse. For a sub that age, it will want airspace to sound good. For a 15 I would give it 3 cubes, ported. Definitely nothing under 2 cubes though.
