About the Kicker 49DL7TDF122
From our tech experts at CEN
The Kicker 49DL7TDF122 is a dual 12-inch L7T square subwoofer down-firing loaded enclosure, rated at 1200W RMS at 2 ohms. Measuring just 21cm deep, the custom-tuned box is designed to deliver powerful bass while preserving boot space. Forced-air cooling supports reliable high-power handling.
Who it suits
This enclosure suits drivers who want serious bass output without losing their boot — particularly truck and SUV owners with shallow space to work with. Those wanting a less powerful option can consider the single 12-inch Kicker 49L7TDF122 at 600W RMS.
Our tech experts advise
You will need an external amplifier rated at 1200W RMS at 2 ohms — this enclosure is not self-powered. At 97cm wide and 43.5cm long, measure your space carefully before ordering. Installation is priced per vehicle; contact our Nottingham team for a fitting quote.

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 size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
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: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
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 does the Kicker 49DL7TDF122 need?
A: Kicker recommends 1200W RMS of amplifier power for the 49DL7TDF122, which presents a 2-ohm load.
Q: How big is the Kicker 49DL7TDF122 enclosure?
A: It measures 43.5cm (17-1/8in) by 97cm (38-3/16in) by 21cm (8-1/4in), in an ultra-thin design intended to save boot space.
Q: Why is the Kicker 49DL7TDF122 down-firing?
A: The down-firing design, together with the tough enclosure, resists stacking weight.
