Overview
A truck cab or trunk with little spare room gets a compact down-firing enclosure from this Kicker, with the woofer facing the floor to use the space under the seat or deck. It is a wired subwoofer in a plastic enclosure.
The 49L7TDF122 packs a twelve inch L7T driver into a slim box meant for trunk mounting. Power ratings are high enough for a serious system, but no amplifier is listed and the unit is not waterproof. Several spec lines, such as voice control and laptop compatibility, look like data errors.
Who it's for
Drivers who want a single twelve inch sub in a shallow enclosure and who already have, or plan to buy, a matching amplifier. A buyer expecting a plug-in powered unit or outdoor exposure should look elsewhere.
Pros and cons
- Down-firing design saves space
- High RMS power handling
- Made for truck or trunk mounting
- No amplifier listed
- Not water resistant
- Odd entries like voice control
- Heavy for its size
Performance notes
Firing downward lets the cone use the floor as a reflector, which tends to reinforce low bass in a small cabin. Output depends on the amplifier supplying the stated power at the stated impedance, and on how the enclosure is positioned in the vehicle.

Frequently asked questions
Is the Kicker 49L7TDF122 a powered subwoofer?
The listing does not list a built-in amplifier. It describes a wired subwoofer enclosure, so assume you need to supply an amplifier matched to the 600 watts RMS and 2 ohm rating.
Can the Kicker 49L7TDF122 go in a boat or open vehicle?
The listing says it is not water resistant, so it is not suited to wet or open locations.
Why does the listing mention laptops and voice control?
Those lines, along with PA use, appear in the spec data but do not fit a car subwoofer. The title and wired connection are the reliable details.
