As part of AlpineÃ¢â‚¬â„¢s reengineered amplifier series, the Alpine PDX-M6 provides optimum performance and reliability. The series is a recipient of an Innovations Honors Award for innovative consumer electronics. With a 95 dB signal-to-noise ratio, the amplifier eliminates background noise and static to produce crystal clear sound. The ampÃ¢â‚¬â„¢s features decrease distortion at higher frequencies, resulting in clear signals where your ear is most sensitive to distortion. The one-channel model delivers RMS powers of 600 watts at 4 ohms and 600 watts at 2 ohms. Compact dimensions of 2 inches in height, 10.13 inches in width, and 7.56 inches in depth ensure that the amp can fit comfortably in any car. If you like to pump up the volume, you can feel reassured by the ampÃ¢â‚¬â„¢s Thermal Protection Circuit, which prevents the amp from overheating for non-stop sound enjoyment.
