Amplifiers with a Power Output Rating of 250-Watts x 1-Channel, 4-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 @ 4-ohm might put out 500-Watts @ 2Ω. 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, 500-Watt @ 2-Ohm or 250-Watt @ 4-Ohm Designed to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the JD500/1 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 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.
