^^^ i agree with that, 18hz can be felt but a setup based on that will be pretty quiet on every type of music thats not chopped and screwed. You would be happy anywhere between 28-33 hz tuning for your box for the lows.
As for batteries, xs power, deka, kinetik, odyssey, sears diehard platinum, sam's club duracel agms or eaton are all AGM batteries you can get.

look up the big 3 upgrade, your gonna need that for sure. It would be wise if you bought a 50 foot spool of 1/0 ofc power wire since this will be a big install and will require several runs of it, try sky high, knu koncepts or execution audio on
ebay or
amazon or hit up
@mylows10 ; he can get you squared away with some sky high wire, terminals and etc. He also has singer alts too.
As for the build, Go big or go home man! If you got good support, you can always learn and improve on the go. It doesn't take a genius to do car audio. It just takes patience, common sense, a willingness to learn and accept advice, But most of all, A big wallet.
