Product Details:


Simply put, Kicker's patented square Solo-Baric subs deliver massive bass. Their cones offer up to 20 percent more surface area than similarly sized round woofers, which lets them push more air, resulting in more low-frequency punch. The Solo-Baric L5 subwoofers feature a rigid stamped steel basket supporting a one-piece cone for increased resistance to unwanted flex — you can push this sub hard without worrying about breakup. Extra venting around the internal structure reduces harmful heat which can lead to distortion and breakdown.

Kicker's Solo-Baric L5 Series 08S15L54 15" subwoofer sports a sturdy polypropylene composite cone and a big Santoprene™ rubber surround for maximum excursion with tight control. A huge magnet and precision-made motor structure contribute to the tremendous bass output, while the matte black finish makes this sub look as fierce as it sounds. Dual 4-ohm voice coils give you the flexibility to build a honkin' multi-sub system or to draw big power from your amplifier.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation. Most mono amps are stable down to 2 ohms.
