About the Kicker 48CWRT104
From our tech experts at CEN
A 10 inch subwoofer from the Comp line, Kicker’s long-running range for solid bass without a competition budget, with a 4 ohm voice coil so it can be wired to suit your amplifier.
Who it suits
Drivers building a system where the bass does real work rather than filling in behind the speakers. 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.
