There isnt nothing "wrong" with JL. Its the prices of a 10 year old designed sub, and a amp that will "mute" itself when the voltage/amperage drops. But it still makes power? how JL huggers say they get loud with out electrical upgrades but even JL recommends a HO for the 1000/1? But its mostly the people that buy JL, stick it in some off the self box and say its the best. They ruin it for the ones that hug JL and have a clue on how to get some decent performance out of it. Its a middle of the road SQ company, IMO a real SQ company dont have budget crap like the WX subs and JX amps. People that compare the price of JL to Hertz/Audison and Mc crack me up.
