They are Pioneer subs, does it really matter that much, probably not.That box is a touch on the small side for 2x 12"s. Give your subs at least 3.5cuft.
Ahhh really u can come up with that answer without any knowledge of the subs.. what if he had a pair of Solo X 12's that take close to 3cubes each12s work just fine in that much space.
