JL Audio JLAMPJD250-1: 250 W x 1 Class-D Monoblock Amplifier

Features:

• Monoblock Class-D subwoofer Amplifier, 250 W x 1 @ 2 Ω / 150 W x 1 @ 4 Ω - 14.4 V
• Designed to produce a healthy 250 W into 2 ohms (14.4 V, 1 % THD), the JLAMPJD250 / 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 through excellent efficiency and ultra low distortion.
• The JLAMPJD250 / 1's controls are located on the input panel, while the power and speaker connections can be found along the opposite end of its extruded aluminum chassis. Signal processing features include a 12 dB / octave low pass filter, through continuously variable frequency selection from 50 - 500 hz, and a variable bass boost EQ.  Dual range, differential balanced inputs are also on hand, capable of accepting line and speaker level signals.  Automatic turn on capability (via signal sensing or DC offset sensing) is standard, alongside a set of preamp outputs so you can easily pass signals to another Amplifier. 
• The JLAMPJD250 / 1 is also equipped through 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. Through the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer level from the driver's seat.
