The Kenwood Excelon KFC-XW800F 8" "flat" subwoofer produces serious bass output in the hard-to-fit areas of your compact car or truck. And this shallow-mount sub measures under 3 inches deep, so you can get creative with your installation. The carbon-glass fiber cone employs a honeycomb pattern to deliver quick response in demanding conditions without flexing. The beefed-up rubber surround maintains control over the cone, minimizing distortion caused by resonance. A die-cast aluminum basket offers a rock-solid housing with plenty of venting to keep the heat down. The silver-plated push terminals offer convenient connections and provide excellent signal transfer.
