About the Kicker 46CWTB82
From our tech experts at CEN
The Kicker 46CWTB82 is an 8 inch weatherproof loaded tube subwoofer enclosure from Kicker's TB range, housing a 2 ohm CompR driver and an opposing passive radiator, rated at 300W RMS with a 600W peak. The thick ABS tube measures 21.6 cm wide by 32.8 cm deep and mounts horizontally or vertically. Grilles are included.
Who it suits
Drivers short on boot space in cars, vans or pickups will find the tube format easier to position than a rectangular box. The weatherproof ABS build suits installs where moisture exposure is a concern. For a step up in output, the 10 inch L7T down-firing enclosure offers 500W RMS.
Our tech experts advise
This is a passive enclosure, so a separate amplifier stable at 2 ohms is required; the Kicker KEY500.1 pairs well at up to 500W RMS. Mounting hardware for both orientations is included in the box. Car audio installation is priced per vehicle — speak to our Nottingham team to arrange fitting.
