If you want to have a high-end subwoofer in your dream car audio system, you must strongly consider the Kicker Q-Class 41L7154. Coming from Kicker's flagship brand, this subwoofer is made to deliver a bass performance you will never forget.
This 15-inch Kicker Q-Class 41L7154 subwoofer comes with a SoloKon polypropylene cone and Santoprene rubber surround stitched together, giving it the robustness to withstand long hours of use and accuracy for low-frequency performance. Kicker's UniPlate technology and its massive vent design allow the subwoofer to cool down efficiently, so it can be used for long hours without heating up.


Its square shape gives the subwoofer a larger surface area for more air movement, resulting in more bass output. The Kicker Q-Class 41L7154 also comes with Kicker's famous Blue Lace spider for improved bass accuracy and volume. Its cast aluminum basket makes the subwoofer an excellent option if you prefer longevity.
Thanks to its massive motor, the Kicker Q-Class 41L7154 can handle a power output of 1,200 Watts RMS at 4 ohms. Its sensitivity rate of 88.6 dB and frequency response of 18 to 100 Hz assure you that this sub has no qualms about going loud at increased volumes with minimal distortion.
