Might wanna think about .33 and a big bank of lithium. You're gonna rise with 3-15's in a big ass box. Not an expert but I just clamped 1600 watts on a 5k with stout electrical and a single 15 rising to 4.3 ohms. Wire down and see that 12k you paid for. Jmo. Saw a scv 6k clamp [email protected] Friday night with 3 Zv5 15's taking it with ease.

Would that be more Musical or more SPl?

Tuning... Tune low and you'll be pretty windy with enough power. Tune higher and you'll be louder. I'd tune to about 33hz personally with those.

Okay just trying to understand the port area because DC doesn't have parameters which sucks so a 180 Square inch of port wouldn't be too big? DC gave me 49w20h31d port 46w 2.5 h25d I believe that's like a 115 square inches of port

I was wrong above. You won't need above 150 sq in of port depending on box sz and power. How much power are you shooting for?

You're going to need to wire lower than 1.33 to get 9k out of that amp. .5 should do it but you don't have that option with dual 2 ohm woofers. .33 is low and I honestly shouldn't suggest something I've never wired to so if it were me I'd wire 2 5k's to 1.33@ .67 each and you'll probably be happy with that.
