This JBL Apex Class D amplifier can produce dynamic sound in your vehicle. A signal-to-noise ratio of 75dB provides fine audio, while a frequency response of 20Hz to 20kHz ensures efficient sound reproduction. This JBL Apex Class D amplifier has an ultra-compact design that can be easily installed in a car, while 750W can provide enough power to produce powerful music. It can handle up to 200W RMS (continuous) (100W x 2) under 4 ohms, and 300W RMS (150W x 2) under 2 ohms, ensuring powerful sound and continuous bridging of up to 300W. Optional all-pass, high-pass, and low-pass dividers provide flexible operation. The 2 ohm and 4 ohm impedance conducts power evenly to keep the speaker at an appropriate level. The sensitivity of 75dB absorbs the high points and low points, thus realizing faithful sound reproduction. Class D circuits ensure reliable power handling. The ultra-compact, weather-resistant aluminum chassis prevents accidental overflow near the speaker. The conformal coated PCB can be used for a long time.
