If you are looking for a flagship subwoofer to replace your car's stock subwoofer, then the Kicker Q-Class 42CWQ104 is maybe the perfect option for you. Belonging to its Q-Class CompQ Series, this subwoofer can deliver a no-nonsense bass performance and can be easily installed on aftermarket enclosures.
This 10-inch subwoofer comes with the famous combination of Kicker's SoloKon cone and Santoprene rubber surround, ensuring an accurate low-frequency performance with minimal distortion while having the durability to withstand the rigors of long usage periods at high volume levels.


It has a cast aluminum basket that comes with perimeter venting to allow the subwoofer to stay cool even if you have to use it for many hours. Its voice coils allow the subwoofer to produce massive bass output with ease.
The Kicker Q-Class 42CWQ104 can handle a power output of 700 Watts RMS and can reach up to 1,400 Watts of maximum power. Its frequency response of 24 up to 100 Hz and sensitivity rate of 85.7 dB allows the subwoofer to give a deep and highly extensive low-frequency performance while being able to go out loud with minimal distortion.
