About the Kicker 46CWTB104
From our tech experts at CEN
The Kicker 46CWTB104 is a 10-inch weatherproof loaded tube enclosure housing a 4 ohm CompR woofer with an opposing passive radiator. It handles 400W RMS (800W peak) and uses a thick ABS tube construction that mounts horizontally or vertically. Grilles are included.
Who it suits
This enclosure suits drivers who need strong bass where a traditional box will not fit — a boot corner, under a seat or in a truck cab. The weatherproof build also suits off-road and outdoor applications. For a more powerful alternative, consider the Kicker 49L7TDF102 at 500W RMS.
Our tech experts advise
The 46CWTB104 has no built-in amplifier; pair it with a separate mono amplifier rated for 4 ohms. Check the horizontal dimensions (27 cm W x 27.3 cm H x 42.1 cm D) before fitting. Installation pricing varies by vehicle — see our car audio installation page for details.
