About the Kicker 51HS12
From our tech experts at CEN
A 12 inch subwoofer supplied in its enclosure, handling 230w RMS, so box volume and tuning are already matched to the driver rather than left for you to work out.
Who it suits
Drivers who want bass without commissioning a custom build. A loaded enclosure is the quickest route to a result that works, because most disappointing subwoofer installs come down to the wrong box rather than the wrong driver.
Our tech experts advise
It still needs an amplifier matched to it and a fused power feed from the battery. How the box is secured matters too: an unrestrained enclosure is dangerous in an accident. 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.
