best sq? best LSQ? best setup? 1 12" aa arsenal d4 vs 2 10" cv vmax runing off a kenwood excelon kac-x10d 600rms at 2ohms i listen to rock, metal, alternative rock, etc accuracy is my main objective here. ported or sealed? thinking sealed is better for tighter bass budget is about $180 for subs any other recommendation in this price range

came across SSA today while shopping for some news subs. i have a kenwood excelon amp which pushes 600rms x1 at 2ohms and its 1ohm stable but with no power rating. i posted on crutchfield.com and by chance someone mensioned the ssa icon 12" that he heard. i dont think i have the power for that sub.... i listen to metal and atternative rock. so i goin for a sq or LSQ kind of set up. buget is $250 max. i build my own box and understand box construction. my old subs where 3 12" kicker comps (my first system so dont bash me about them. lol) just looking for something that will keep me satified for the next couple year while im at college. so this is basicly my only upgrade ill do to my system for the next 4 or more years. i was led to believe that the only good stuff was the name brand (kicker alpine etc) so thats what i bought and i hate name brands. i was look at a few option that seem fessible with my amp but im open to all ideas. how are asendent subs i was looking at the arsenal AA 12 D4 for $175 which would leave me some money for a nice box. ive heard cerwin vega's vmax subs are good for the money any input would be greatly apprisiated. thanks current system: sony cdx-gt310 polk db 525 and db1000 (front) polk db 690 (rear) kenwood excelon KAC-X10D Tsunami 1.2 Farad Kicker 4 gauge kit dynamat extreme in trunk
