Please use punctuation in your sentences. Bass is mono and if i recall im running my sub of a monoblock amp. Sure you can have bass in stereo, but the way songs are setup most of the time the basslines are in the center of the soundstage. Really no need for a left and right when both subs are in your trunk and not left and right of you.
Ported is louder. Sealed is more efficient. You dont need multiple subs to hit hard. Like i said, you can buy a stronger sub and amp that is matched to it.
A single sub and amp will not blow your speaker. Im running an Audioque SDC 2.5 with 500rms @ 2ohms. The sub is rated for 600rms and no its not going to blow. And if it did...recone.
Are you against sending lots of power to a single sub? They do make subs that can push 2000rms now all day long on music not just burps.
Those kickers suck imo...much better out there. Especially the solobarics. The world records in db arent held by kicker or mtx or even JL. I believe its DC right now. Followed by Digital Designs and some with Audioque.
Ive heard single sub system put multiple sub systems to same. Its all about the right setup. Just informing the op that you can do a lot with one sub. Did you really say to go buy a crunch amp? Lmao im not a newbie with car audio...my amp is also an Audioque amp and if you wanna check it out its not a light weight:
