My friend still has a pair of these collecting dust in his closet. When I was first getting into car audio I bought a pair of 12" W1s for my car while he had these and a JBL 600w amp. In my car (because of the amp I was using) my JLs hit harder, and the pair cost only $105 (eBay). However, we decided to switch subs for a day, and needless to say the difference between these Xplods and my JLs was unbelieveable. The sound quality took a quantum leap, and the overall volume at least doubled. I would not recommend these subs, simply because they are not worth three hundred bucks.
