Okay, it's that time, upgrading my subs from m1 to m2 (well all the stuff that's on m2s..) so I'm building a new box. What volume should I lean towards and port area? Should I do aeros or slotted.. I just want my subs to be loud and push air...Running ~2,100rms to both subs off of a db drive okur a7 2000.1 amp at .5 ohms. (Subs are 12") Thanks for the responses.
