About the Kicker 45L7R122
Upgraded for even better bass
Upgraded for even better bass
Kicker created their L7 square subwoofers for people who want serious, unstoppable bass, and now their latest L7R Series subs give you that powerful performance with a more friendly price tag. The 45L7R122 12" component subwoofer handles up to 600 watts RMS, enough power to fill any vehicle. Its innovative square cone moves much more air than a conventional 12" round cone, and this sub's made to take anything you can dish out.
Made to take it
The woofer's injection-molded SoloKon™ polypropylene cone features special back bracing for extra stability, while heavy-duty red stitching connects the rubber surround to the cone. The steel basket offers the strength and stiffness that helps the cone maintain its shape during heavy play. The sub's two 2-ohm voice coils give you extra flexibility in incorporating this sub into your system. And the UniPlate™ back plate and pole piece are made as a single, solid unit to allow heat to escape the motor more easily. This Kicker sub is designed to deliver the power of your music without compromise.
To drive this single subwoofer, we recommend a mono amplifier rated between 450 and 900 watts RMS at 1 or 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Dual Voice Coils: For increased system flexibility, the woofer has two 2Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 1Ω load; when wired in series, the woofer presents a 4Ω load.
Square Design: By making the Solo-Baric square, Kicker is giving you the most possible cone area (Sd) for a given size baffle, 16% to 20% more area than a conventional round subwoofer. More cone area means the cone moves more air, resulting in louder, deeper bass.
Cone Material: The square SoloKon design is a unique one-piece construction, using injection molded polypropylene that moves as a lightweight piston, for improved control. A rear cone brace integrates into the cone with a continuous contact perimeter weld, which improves strength and resistance to deformation under pressure.
Surround: The tough, flexible Santoprene rubber surround has a long-throw, positive-roll design, which controls extreme cone excursion and is tear-resistant. The corners of the surround are ribbed to ensure linear cone motion. The surround is stitched to the reinforced cone edge to improve durability.
Speaker Terminals: The terminals are spring loaded and nickel plated for solid connections with speaker wire up to 10 gauge.
Break-in Period: Due to the complex nature of Kicker Solo-Baric L7R woofers, they require a break-in period in order to produce optimum bass response. The high-performance suspension system makes the speakers very stiff out-of-the-box. Approximately two weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. A broken-in subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.
