Car audio subwoofers take more abuse than any other car audio component, making thundering bass for hours on end. For a car audio enthusiast, there's nothing worse than a broken sub. At JBL, we thoroughly test our designs before we deliver them. JBL woofers have to pass a 100-hour power test, where the RMS and peak power levels are tested simultaneously. When you see ‚¬Ëœ300 watts RMS' and ‚¬Ëœ1200 watts peak' in our ratings, you can be sure that those numbers are tested and verified. Additionally, to be sure the moving parts are robust; we subject every design to a proprietary mechanical power handling test at up to 17 times the RMS power handling rating. That means these woofers have to survive test signals as high as 6000 watts. We're fanatics about product quality.
