JBL BassPro SL Loaded Subwoofer Enclosure: Enjoy booming bass on your next road trip thanks to a 125W integrated Class D amplifier for balanced high- and low-frequency sounds. Custom electronic circuitry ensures lush audio and a wide range of output levels.
This equipment puts out a weak bass. Was looking forward to installing this as part of my system. I listen to a lot of very heavy metal and this is disappointing.
