Quick Review:

JL Audio is known for their incredibly well performing and high quality products, and the 8W3V3-4 8″ subwoofer is consistent with that reputation. The W3v3 subs feature a unique motor assembly that provides consistent and precise sound/cone movement at any power level that it's rated for, without distorting. These subwoofers also have an innovative cooling system (Elevated Frame Cooling) that allows air to directly cool the voice coil of the subwoofer, which in turn increases the power handling and quality of sound. Overall, the JL Audio 8W3V3-4 is a very well-rounded, high quality subwoofer that will surely enhance your audio experience in your vehicle.
