JL Audio JX500/1D - mono amplifier 500Watt

Compact gunpowder pack
This robust and reliable class D monoblock uses a robust MOSFET power supply design that provides rock solid bass performance at a very affordable price. The JX500/1D is made especially for subwoofer applications and has a variable low-pass filter with stepless crossover frequency between 50-200 Hz. It also has a variable bass boost at 45 Hz. with up to +12 dB and an optional remote control boost control (RBC-1). Dedicated high-level inputs are integrated, in addition to conventional low-level RCA inputs, making it easy to integrate with a range of OEM and aftermarket head units.
