The HYANKA CDP-1200D/1500D is a Class D mono amplifier designed to drive car subwoofers, delivering RMS power of up to 1200/1500 watts and stable seamless operation at 1/2/4 ohms, making it perfectly suited for most car subwoofers. The unit also uses a MOSFET power supply for higher speed, lower loss rate, and lower noise. The amplifier features an adjustable bass boost (0/6/12dB) that allows you to crank up the intensity of the bass for a louder and more powerful bass effect. In addition to this, crossover controls for subsonic filters, low pass filter and input gain are supported, allowing you to adjust them at will to achieve the audio output you want. The amplifier also comes with a remote dashboard subwoofer controller, which allows you to adjust the bass volume more conveniently without having to operate it through the amplifier. This amplifier has been designed to be compact by engineers using a combination of high quality parts and aluminium enclosures, and is rigorously tested both at the semi-finished stage and in final assembly to ensure the highest quality product reaches you. If the product does not perform as you expect, you can also return the amplifier directly within 90 days for a full refund.
