Amplifiers with a Power Output Rating of 250-Watts x 1-Channel, 2-Ohm Final Impedance

Amplifiers with a Power Output Rating of 250-Watts x 1-Channel, 2-Ohm Final Impedance

RMS power: This rating of any amplifier is the continuous power rating that an amp is designed to output at a maximum continued volume rating. The RMS power specification is one of two numbers to go by when pairing your speakers with an amplifier, not the only 2 but a good starting point. As an example, a speaker driver with a 250-Watt, or 250W for short, RMS rating should be paired with a two-hundred-fifty-watt RMS amplifier. We usually recommend an amp to be over powered by 10% RMS so that the power-plant does not have to work at 100% capacity to get 100-percent efficiency from your speakers. This will keep your amplifier from overheating during long periods of continuous operation.

Ohms: Is the resistance rating of an amp and is the second most important when pairing drivers with amplifiers. A power-plant that is 250W @ 2-ohm might only put out 125-Watts @ 4Ω. When purchasing an amplifier, the correct pairing of a speaker’s RMS wattage and Ohm ratings with an amp’s output power rating is absolutely essential.

    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.

    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.
