I love my JL subs... I have one 12" w6 and a pir of 8s in my 72 saab wagon Go great with the MBQuart Pro 6.5 components driven by a pair of Soundstrea pro amps. 200 front and 300 to the subs. Gallery Images
JL makes a great product, I used to be a salesmen at JL Authorized dealer. The WO is a great bang for the buck subwoofer and can really pound with only moderate amounts of power. As you go up the line you may get more total output and power handling, but a pair of 10w0's with about 150-200 watts each can pound really hard and sound really clean.
