Monoblock Subwoofer Amplifier

The JL Audio JD500/1 is a monoblock subwoofer amplifier engineered to deliver 250 Watts RMS at 4 ohms or 500 Watts RMS at 2 ohms. Built with a highly efficient Class-D design, this compact unit is intended for space-conscious installations and is optimized for powering subwoofers to achieve significant low-frequency performance. Equipped with proprietary Nex-D Switching technology, the amplifier utilizes a self-oscillating modulator to produce clean bass while minimizing noise caused by fluctuations in supply voltage. The unit also features Differential-Balanced inputs to effectively cancel out induced cable noise, a common issue in mobile audio environments. Technical specifications include a frequency response of 7 to 500 Hz and a sensitivity rating of 80 dB to ensure loud, low-distortion playback. Installation requires 4 AWG power wire and includes a variable low-pass filter (50-500 Hz) along with a variable bass boost up to 12 dB for custom sound tuning. The amplifier comes with a 2-year warranty and includes necessary hex keys for installation.
