Description
Included in this kit
JL Audio Two 12W0v3-4 Subwoofers with JD250/1 Bass Package - Two 12" W0 Subwoofers with 250 Watt Monoblock Amplifier
W0v3 12-inch Subwoofer Driver (300 W, 4 Ω)
The 12W0v3 is a rugged performer with excellent efficiency, excursion capability and linearity. Its overall performance envelope that puts it right at the top of its price class. It features a beefy 2 in. diameter voice coil and our patented Elevated Frame Cooling design for enhanced power handling and reliability.
The 12W0v3 is best used with amplifier power in the 75W - 300W range and is optimized to operate in a moderately sized 1.375 cu. ft. (38.9 l) sealed enclosure, or a 1.75 cu. ft. (49.6 l) ported enclosure.
JL Audio JD250/1: Monoblock Class D Subwoofer Amplifier, 250 W
JD Amplifiers redefine a high-value package in terms of performance and efficiency. JL Audio’s NexD™ switching technology and clipping indicators (for ease in setting Input Sensitivity), add tremendous bang for your buck. Their dual-range, differential-balanced inputs minimize noise, while maximizing compatibility with a wide range of signal levels. Monoblock models also include variable bass boost and Remote Level Control capability when used with an optional RBC-1 Remote Bass Control.
They fit nearly anywhere!JD1000/1: 11.40 x 7.50 x 2.10 in. (290 x 190 x 53 mm). High-mass heat sink improves thermal capacity leading to reduced incidence of shut-down events.
NexD™ Switching Amplifier Technology: Our high-speed switching technology delivers outstanding fidelity with very low noise and distortion. Exceptional efficiency results in reduced current draw and heat, permitting reliable high power output within a very small chassis. Specifically optimized for subwoofer applications (7 Hz - 500 Hz bandwidth).
Complete Signal Processing Package: 12dB/octave low-pass filter, non-defeatable, with fully variable filter frequency selection from 50-500 Hz. Adjustable 0 to +12 dB Bass Boost EQ @ 45 Hz. Remote level control with optional controller (RBC-1). Preamp outputs (buffered, pass-through type)
Dual-Range, Differential-Balanced Inputs and Automatic Turn-On CapabilitiesBenefits: NO NOISE! Outstanding noise rejection prevents alternator whine and other noises. Accepts line-level or speaker level signals (up to 8V RMS), including those from factory systems, without a line-output converter (LOC): just splice wires to a pair of RCA ends or RCA cables. Automatic turn-on option via Signal-Sensing or DC-Offset sensing
Integrated LED Clipping Indicator for Easy Setup: Simplifies input-sensitivity setting by providing accurate visual feedback of output clipping level.1) Disconnect one speaker output wire, 2) Play full-scale (0 dBfs) sine-wave through audio system, with head unit at 3/4 volume and tone controls set flat, 3) Adjust input sensitivity until light turns on, then back off slightly. Separate, top-mounted LEDs report overall status and condition
