doesnt need to be super loud. going into an aparment, probably a dayton 240 amp.

any sq sub will work, tune the box low, mid 20's.

It depends on what box you're going to use.

Typically, I look for one with a soft suspension, low Fs, high xmax, medium/high bl, and qts depends on your application. Efficiency really isn't a big factor, similar to car audio.

There are not many car audio subwoofers that are very accurate for t/s though since most are mass produced.
