I have 1 JL w1 10' and it cost 100$ at my local sterio shop, it thumps hard and takes very little juice to push it. i have 1 amp (400 watts) that runs my highs and lows, so i only have 200 watts to the sub and its almost to much power. i constantly get comments and how my stereo system sounds... of course my highs are all mb quarts, that helps too. JL i the way to go, simply put. My best friend was a stereo installer for a high end place called Rolling Thunder in San Rafael CA, he's done stereos for superstars. So thats where my opinion comes from.
