About the Kicker Q-Class 42CWQ154
L7 + round frame = CompQ
L7 + round frame = CompQ
When Kicker introduced their L7™ series subwoofers, the combination of rugged materials, quality workmanship, and innovative design raised the bar for aftermarket subwoofer performance. Now Kicker has created the CompQ™ Series subwoofer, a speaker that puts the L7's awesome performance into a round basket that'll mount in a standard enclosure.

Built tough for great bass
The 42CWQ154 15" sub features a forged aluminum frame for maximum strength and accurate sound reproduction. The sub's injection-molded SoloKon™ polypropylene cone features special back bracing for strength and responsiveness, while a special-design Santoprene™ rubber surround allows greater cone excursion for increased output. Two 4-ohm voice coils make it easy to get more power from your mono amplifier.
Handles up to 1100 watts
This sub's advanced design keeps things cool when you are driving your system hard, so you'll get reliable performance. With up to 1100 watts of RMS power handling, you'll get plenty of the deep, rich bass you need to make your music come alive.
Kicker Q-Class subwoofers incorporate cutting-edge technologies and superb construction to deliver an extraordinary musical experience in your vehicle. These subs are only sold by select dealers chosen by Kicker.
