150W x 1 @ 4Ω

JD-Series Monoblock Amplifier, 250-Watt @ 2-Ohm or 150-Watt @ 4-Ohm Designed to produce a healthy 250 watts into 2 ohms (14.4V, 1% THD), the JD250/1 amplifier is a great solution for powering subwoofers in a cost-conscious system. JL Audio's proprietary NexD™ switching technology delivers large amounts of real-world power output with excellent efficiency and ultra-low distortion. The JD250/1’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 JD250/1 is also equipped with 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. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer level from the driver’s seat.

Kicker KEY-Series Mono Amplifier with Automatic EQ/DSP Processor, 300-Watts @ 2-Ohm Kicker KEY series amplifiers use a powerful internal computer to deliver dramatic improvements in realism and soundstage. A massive 40-band equalizer improves tonality, and a 24dB crossover re-defines the capabilities of each speaker. The KEY500.1 delivers 300 watts RMS of power to your speakers at 2-ohms. Measuring less than eight inches long and only two inches high, the KEY500.1 fits nearly anywhere. Mount it behind your radio, under the seat, or in your trunk with ease.  If the temperature reaches the threshold, the Kicker KEY500.1's dynamic power-management algorithms kick into gear! Instead of hearing the amplifier's volume “pumping” or blowing a fuse – KEY technology engages a nearly inaudible limiter/compressor, applied only to the peaks of the music for as little as milliseconds at a time. The amplifier quickly cools, which deactivates the compressor. Music returns to its full dynamic range without a moment’s interruption!

RP-Series Monoblock Subwoofer Amplifier 350-Watts @ 1-Ohm, 250-Watts @ 2-Ohm, 150W @ 4-Ohm Skar Audio engineered the RP-350.1D Class D monoblock subwoofer amplifier to be dominant in both power and reliability compared to anything else on the market in its class and physical size. Designing the most efficient, well built, high quality amplifiers is where we start here at Skar Audio, and that is exactly what is delivered in this unit. The smallest of all RP series amplifiers, the RP-350.1D is the perfect solution for when you need versatility but are not willing to sacrifice power output. The RP-350.1D is 1-ohm stable and utilizes a wide array premium internal components that make it extremely powerful and reliable - such as its high speed MOSFET power supply and advanced PCB board layout. Conservatively rated at 350 watts RMS power at a 1-ohm load, with the capabilities of reaching beyond 388 watts at max power output. This compact, small footprint amplifier, is by far one of the most affordable monoblocks Skar Audio has ever released, and is great for powering a pair of subwoofers rated around 200 watts RMS each or a single subwoofer around 400 watts RMS. In addition to all of the above features, the 4 gauge power and ground terminals found on the amplifier allow for maximum current flow and therefore higher power output and more efficient operation. Furthermore, you'll have full reign over your amplifier with the built-in user control panel, featuring a bass EQ switch (0, +6, +12dB), and variable adjustment tunings for gain level, low-pass filter, and subsonic filter. Featuring 4-way protection circuitry, you'll have the peace of mind knowing that you are protected against damage to the amplifier for various reasons - including electrical shortage, over heating, low voltage, and more. This amplifier comes with a remote subwoofer level control (bass knob) allowing the user to have full control over their bass from the front of the vehicle.
