Kenwood eXcelon KFC-XW800F 8" Car Subwoofer 600W Max 150W RMS 4-Ohm

The Kenwood eXcelon KFC-XW800F 8" shallow-mount car subwoofer is built for installs where mounting depth is limited but clean, usable bass still matters. Its carbon-glass fiber honeycomb cone, aluminum die-cast basket, and shallow profile make it a strong fit for trucks, compact custom enclosures, and space-conscious builds where a standard deep-frame subwoofer will not work.

For properly matched mono amplifiers and tight-space enclosure designs, the KFC-XW800F delivers 150 watts RMS handling, 4-ohm compatibility, and the controlled low-frequency performance expected from Kenwood’s eXcelon line.
