I am in a debate about which two 12's i want to buy and i just want subs that are going to rock the streets like no other. SHould i get shivas, hx2's, or audiobahn ultra, high, alum, or flame q subs? THey will be powered by the JBL1200.1 in any box. If you guys could tell me the loudest sub in the best box for it it would be sweetness. Thanks.
