JL Audio 12W6v3-D4 with XD600/1v2 600 Watt Subwoofer Kit

The JL Audio W6 subwoofers were forever considered the best subwoofers on the market, prior to the release of the W7.  Now on their generation, the W6 offers unmatched output and sound quality, while performing with very little air space requirements.  The 12W6's recommended enclosure volume is only 1.0 cubic feet, the same size used for many compact 10" subwoofers.  The 12W6 is very efficient, performing with 200-600 watts of RMS power while still giving you accurate, clean bass response.  The XD amplifiers are rock solid when it comes to both output and sound quality.  Compared to the less expensive RD and JX, the XD is going to sound better, you can drive it harder, it will have more raw output, it has better signal processing, and the chassis is pretty compact.  They are just all around, better amplifiers.  The XD600/1v2 amp is amazing and for a mono amp, you get many of the technologies used in the HD and the Slash, in a smaller, more affordable package.
