II am going to use to buy a M&K plate amp off craigslist for $175 shipped. It does 250 watts RMS @ 8ohms, which should do this sub plenty justice. It achieves full excursion at only 150 watts RMS, but can handle 300.
I'd say dude inverted the sub because of it's ridiculous mounting depth. And yes, they can be used in car audio applications.Does the sub have to be inverted or did you just choose to do that? Also, do these subs sound good in just a home theater application or car audio as well?
