JL Audio Dual 10" Subwoofer Bass Package - PPJLA7 Package Includes:One - JL Audio CP210W0v3 Loaded 10" Dual Subwoofer EnclosureOne - JL Audio JD500/1 500 Watt Mono Subwoofer Amplifier JL Audio CP210-W0v3 Dual 10W0v3-4 Loaded Subwoofer Enclosure This powerful slot-ported BassWedge™ subwoofer system delivers awesome output at an unsurpassed value. The slot-port runs along the bottom of the enclosure and fires on the same plane as the woofers to produce excellent extension and response smoothness. The port mouth is flared to minimize air-flow noises. The ultra-versatile BassWedge™ shape has extended sides so that it can be placed with the woofers firing out or straight down, off the floor of the vehicle. The shape works equally well in forward or rear-firing installations. This gives you plenty of options for tweaking the loading of the enclosure into your vehicle. This subwoofer system is shipped wired, loaded and ready to connect via a push-button terminal.

Our proprietary NexD™ switching technology delivers large amounts of real-world power output with excellent efficiency and ultra-low distortion. The JD500/1’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, with 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-level and speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier. The JD500/1 is also equipped with an onboard LED-clipping indicator ring, surrounding the input sensitivity control. This useful feature lets you 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.
