i've never been a big fan of MTX Subs, just a lack of sound quality, although i've never messed with any of there products since like 06 or 07. I loved there amps but the subs seem like they just go for loud, and not clear, which a few years ago was what i was all about. Now i want loud but clear...if the person behind me can't hear my mids and highs too, then i don't want it lol
