Included in this kit
This bundle includes a JL Audio RD1500/1 Monoblock Class D Full-Range Amplifier, 750 Watts x 1 @ 4 ohm / 1500 Watts x 1 @ 2 or 1 ohm - 14.4V, and 2x JL Audio 13W3v3-4:13.5-inch (345 mm) Subwoofer Driver 4 Ohm.
1x JL Audio RD1500/1 Monoblock Class D Full-Range Amplifier, 750 Watts x 1 @ 4 ohm / 1500 Watts x 1 @ 2 or 1 ohm - 14.4V - (RD1500/1)
Monoblock Class D Subwoofer Amplifier, 1500 W x 1 @ 2 Ω AND 1 Ω / 750 W x 1 @ 4 Ω - 14.4V
Purpose-built for subwoofer applications, the RD1500/1 monoblock amplifier delivers 1500 watts of jaw-dropping bass output into 1 OR 2 ohms (14.4V, 1% THD). At the heart of this ultra-sleek and compact power plant is JL Audio’s exclusive NexD™ Class D technology, permitting high power output with exceptional efficiency and low distortion.
For your convenience, all of the RD1500/1’s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its 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-balance inputs are also onboard, capable of accepting most input voltage levels. 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 RD1500/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity setting, quickly and accurately, with no special equipment needed. The RD1500/1 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition. Control of the subwoofer level from the driver’s seat is easily accomplished with the addition of the optional RBC-1 remote level control (sold separately).

2x JL Audio 13W3v3-4:13.5-inch (345 mm) Subwoofer Driver 4 Ohm - (13W3v3-4)
JL Audio 13W3v3-4
W3v3 13.5-inch Subwoofer Driver (600 W, 4 Ω)
If you have the space, it makes a tremendous sense to maximize your subwoofer system's piston area to enhance efficiency (and output). It gets even better when the larger driver delivers additional power handling and excursion. For the preceding reasons, the 13W3v3 can be the best choice for those seeking high output with great sound quality at medium power levels.
As with the smaller W3v3's, several exclusive JL Audio technologies and proprietary assembly techniques are applied to the 13W3v3 to enhance linearity and reliability.
The 13W3v3-4 is best used with amplifier power in the 150W - 600W range and is optimized to operate in a moderate size 1.5 cu. ft. (42.5 l) sealed enclosure, or a 2.25 cu. ft. (63.7 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.
