About the Kicker 45L7R122
From our tech experts at CEN
The Kicker 45L7R122 is a 12-inch square subwoofer from the L7R range, handling 600W RMS (1200W peak) with dual 2-ohm voice coils. Its square SoloKon cone delivers more surface area than a round 12-inch driver, producing deeper bass without requiring a larger enclosure.
Who it suits
This sub suits enthusiasts who want to specify their own enclosure and amplifier for a custom installation. It works in sealed (24.92–56.64 litres) or ported (49.6–92.0 litres) boxes. If you prefer a ready-made option, consider the Kicker 49L7TDF122 12-inch L7T down-firing loaded enclosure.
Our tech experts advise
This listing is a bare driver — you will need an enclosure and an amplifier rated to 600W RMS. Wire the dual 2-ohm coils in series for 4 ohms or in parallel for 1 ohm; confirm your amplifier is stable at the chosen impedance. Mounting depth is 17.4 cm, so measure your enclosure carefully before ordering. Fitting is priced per vehicle — speak to our installation team for a quote.
