Those mm 15's are just hard to come by now...if I can find one I'll find a use for it...if it don't fit right in the truck I could run it as a front sub in my saturn from 60ish-150ish for a big azz mid bassPolk still makes a quality product. I really like the Older MoMo series . The DB series is a nice budget and even medium buy purchase for the Audiofile/, but i do feel like the MM series is pretty top notch for the price point and really perform very well and seem to last
