About this item

  • 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.

This fit under my seat in my 2014 Chevrolet double cab perfectly. I always have preferred ported boxes and wasn’t sure about the shallow sub design and sealed box , but man this thing is super impressive. It covers a wide range of bass from punchy bass to the low frequency bass . I upgraded from kickers L5s and wow what a difference , if you’re on the fence on buying these just do it you won’t regret it. Great job Kicker!

I've had other big systems and I was a little weary these would just be okay, but I'm blown away. They sound great with a 1200RMS/2400 watt Kicker amp.

Fits perfect under my rear seat of my Silverado. Bass sounds sweet. Nice deep bass. Kickers are the way to go.
