JL is very high-quality...
not to mention the name...
most of the time (exept on this forum) when you open up ur trunk and have W7's sittin there you are gunna have a jaw drop....
it's like a status thing and jl amps are VERY nice IMO
Jl has almost no competition in their home theater sub line, and also make some of the best marine equiptment (kicker makes some nice stuff too)
but all in all there aren't many subs that compete with the w7 in the combination of SPL and SQ, and even those that do probably aren't even close to as recognized as the W7... (99% of people probly have never heard of companies like RE, FI, or DD)
so imo for the adverage competitior, JL isn't the best choice very often...
but for the adverage street going dude who wants a LOUD system that sounds crystal and makes his friends go DAAAAAMN! jl is a great choice
and lets not forget aesthetics, jls stuff just LOOKS good too
