It doesnt matter whether the sub is car audio or home audio, as long as it can take the power , have long xmax. home and car subs have similar parameters.
There are plenty of 12" car subs that would operate in 1.5 ft3 sealed, Try rockford fosgate, JL audio, Mtx, kicker solobaric and other good branded subs, Dont bother with the cheap ones, They're not worth the money, They wont be as good as the more expensive ones.
I also recommend the Dayton RSS315HF-4 12" Reference HF Subwoofer 4 Ohm , it would work well in a 1.5 ft3 box. I'm about to buy 2 myself. And it's reasonably priced at $138- at PE.
