Made to match every curve and contour, these loaded truck boxes are custom-made to fit perfectly under your back seat. Tough MDF construction and thick internal bracing keeps the enclosure stable, even with extreme bass. Covered in durable black carpet and sporting a custom KICKER logo, these enclosures are pre-wired to a single two-Ohm terminal for maximum output. All you need is an amp! KICKER signature-square, sub-design technology has nearly 20 percent more cone area than comparable round subwoofers, moving more air and producing louder bass in the same space! A next-level top-plate design, unique heat management system and our signature cone stitching all help to give you deep bass and outstanding reliability! The L7T features Forced-Air Cooling, creating high power handling and ultra reliability. As the woofer's cone moves downward, hot air around the voice coil is forced out of the woofer. As the woofer's cone moves upward, cool outside air is drawn into the woofer cooling the voice coil.
