About the Kicker 45L7R124
From our tech experts at CEN
A 12 inch subwoofer from the Solo-Baric L7 line, whose square cone gives more radiating area than a round driver of the same nominal size, with a 4 ohm voice coil so it can be wired to suit your amplifier.
Who it suits
Drivers who want serious output and have the space and the amplifier to do it justice. It needs an enclosure sized correctly for the driver: sealed for tight and accurate, ported for louder and deeper.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier behind it. Box volume, port tuning and how the voice coils are wired decide what you actually hear. We build enclosures to suit the vehicle and match amplification at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.
