In order:
Shiva 2 12 "
Oz Audio Matrix 250l 10" (but you may want to step up to 12's)
JL Audio 2 12W3
Pioneer 2 12" Pioneer TSW 3041 DVC
This is my opinion, OZ makes a nice sub and its a shame that they are so slept on, but if you take a look at the Vortex its a nicer sub then the one you have listed. Really good SQ in OZ subs. . .
