I have a 12" MYX blue thinder in a ported box that I made myself..
I don't know what series. but I know it is the competition series that the MTX truck has in it.
anyways. the things punds major.
MTX has got to make on the the best sub.
jbl is good too. they are more of a clean sound.
if you want power then stick with MTX
