Anyone ever heard of em, opinions and whatnot. Thanks.

good stuff, known more for SQ than for SPL. i had four of their subs in my ranger and they sounded great but were spl limited.

my friend has a 15" vector seris that's a couple years old and just wondering if ti's worth it, he's asking 200 with a ummm super cool? scosche amp

depends on the amp, but don't get your hopes up for a lot of output from that sub.
