ok guys i searched this and had no luck..
im getting a 15" sub and an amp to peak it out soon

its between JL W7 13.5, MTX 9500 15", Kicker Solo-baric L7 15"

the peak power is about the same on all of them i was thinking a hifonics brutus 2000 watt peak amp

Any body have any of these subs or know about which is best?
thanks~

MTX T9500 hands down!! They are stupid loud! I put 2 of these in a Caddy ESV last year on 2 MTX 1501D 1500 watt mono's it was insanely loud! The JL 12w7 is $300 more than the T9500 but for 300 in price difference the .03 in volume difference doesnt make sense. The T9500 takes a small box also, big puls in my book.

check out his link!

Select MTX T9500 on the left column and the JL on the right. Then do the same against the Kicker L7!

Digital Designs 3515/ 9515, Treo SSi 15/ SSX 15, RE SX15/ XXX15. Id take any of these subs over the three you just listed for high power handling and good quality subs.
Dave-
