orion hcca 10.4 vs solo x 10 1ohm

use the solo-x my friend... but first.. get another 1500.1... build a enclosure vented at about 2.5 to 3 cubic feet.... call kicker tech support and they will bless u with the wisdom to terrorize your neighborhood relentlessly......... enjoy..... otherwise.. u kinda got the wrong subs to do sealed with... the orion will probably sound a lil more accurate sealed... what u really need is like a 12w6 jl.... or even a cvx12..... u got a lot a power with that amp... but those subs are designed for your desired application..... but u don't have the power to really make that solo-x sound good sealed.. thats where the second 1500.1 would be handy... otherwise... u can still do a relatively small ported enclosure to help make up for the lack of wattage u have.......there can be only one.......
