L7T 12" down-firing loaded enclosure, 2 ohm

The Kicker 49L7TDF122 fits a 12" square subwoofer into a slim, ready-to-fit enclosure — ideal where boot space is limited but bass quality is not negotiable.

At 600W RMS, the L7T delivers serious low-end output. Kicker's square sub design uses nearly 20% more cone area than a comparable round subwoofer, moving more air and producing louder bass without requiring a larger box.

The down-firing enclosure is built from thick MDF with internal bracing. It resists flex, stacked weight and surface scratches, so luggage can be loaded on top without risking damage to the driver below.

Forced-Air Cooling keeps the voice coil temperature in check. As the cone moves down, hot air is pushed out; as it moves up, cool air is drawn back in. This delivers consistent performance and long-term reliability at high power levels.

Features

  • 12 inch L7T square subwoofer
  • 2 ohm impedance
  • 600W RMS power handling
  • Down-firing design provides protection for the subwoofer driver
  • Thick MDF construction with strong internal bracing

About the Kicker 49L7TDF122

From our tech experts at CEN

The Kicker 49L7TDF122 is a slim, sealed, down-firing loaded enclosure housing a 12 inch L7T square subwoofer, rated at 600W RMS (1200W peak) at 2 ohms. It measures 38.0 x 60.5 x 16.7cm. Kicker's square cone design gives nearly 20% more cone area than a comparable round driver, moving more air without needing a larger box.

Who it suits

This suits drivers who want strong bass but have limited boot depth. The down-firing design means luggage can sit on top without risking the driver. For a slightly smaller option, consider the Kicker 49L7TDF102 10 inch L7T enclosure.

Our tech experts advise

This enclosure has no built-in amplifier, so you will need a separate unit rated stable at 2 ohms — the Kicker 47KEY500.1 is a suitable match. Measure your boot carefully before ordering: the enclosure is 60.5cm wide and 16.7cm deep. Installation is priced per vehicle; see our car audio installation page for details.

Frequently Asked Questions

Q: Do I need an amplifier for this subwoofer?

A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.

Q: What does RMS power mean?

A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.

Q: Can CEN build or supply an enclosure and fit everything?

A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.

Q: What amplifier should I pair with the Kicker 49L7TDF122?

A: Choose a mono amplifier that delivers around 600W RMS into 2 ohms, matching the enclosure's 600W RMS rating and 2 ohm impedance. The enclosure has no built-in amplifier.

Q: Do I need to build a box for this subwoofer?

A: No. The 12 inch L7T subwoofer comes factory-loaded in a sealed, down-firing MDF enclosure, ready to fit.

Q: How big is the Kicker 49L7TDF122?

A: Kicker lists it at 38.0cm high, 60.5cm wide and 16.7cm deep.
