JL Audio JD250/1 Class D Amplifier and JL Audio 10W0v3-4 10″ Subwoofer Bass Promo Package
Amp Highlights
Designed to produce a healthy 250 watts into 2 ohms (14.4V, 1% THD), the JD250/1 amplifier is a great solution for powering subwoofers in a cost-conscious system. Our proprietary NexD™ switching technology delivers large amounts of real-world power output with excellent efficiency and ultra-low distortion.
The JD250/1 is also equipped with an onboard LED-clipping indicator ring, surrounding the input sensitivity control. This useful feature lets you easily set your amplifier’s input sensitivity, quickly and accurately, without special equipment. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer level from the driver’s seat.
