I was going to buy 2 JL W3's but now having read many posts I dunno what to buy. I have heard great things about eclipse and alpine subs and I have heard many JL woofers. Please help me decide which to buy. I would like two woofers (if only one it has to have some nice thump) and I would like to spend less than $600 on the set or one woofer/s. Any advice would be thanked!
