Want more sound in your car without sacrificing the entire trunk? These new JL Audio XD amplifiers should help. The XD500/3 is a three-channel, 500-watt amp that’s designed specifically to power a set of component speakers and a subwoofer system. It features JL’s NexD switching technology that allows the main channels to produce 150-200 watts total, giving high-quality component speakers plenty of power. The dedicated sub channel can produce up to 300W of low-frequency power. Studio-grade signal processing also features variable crossover filters, two- or four-channel mode selection, assignable pre-amp output source and remote level control modes.
