About the AudioControl EPIC X8D2
From our tech experts at CEN
An AudioControl 8 inch subwoofer, 2 ohm, handling 400w RMS.
Who it suits
Drivers building a system where the bass does real work rather than filling in behind the speakers.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier behind it: box volume and tuning decide what you actually hear, and impedance decides how it should be wired. We build enclosures to suit both driver and vehicle 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.
