The Skar Audio SK-M9005D full-range five channel amplifier offers high performance from an ultra-compact chassis. This Class D amplifier uses less power, takes up less space, and generates less heat than traditional amp designs, making it the perfect solution when space is at a premium and sound quality is the ultimate goal. Don't let its size fool you, the SK-M9005D boasts an impressive 900 Watts of power, providing the versatility to power multiple sets of speakers as well as a subwoofer system.
The SK-M9005D provides you with the tone controls you need to tune your system so that your speakers and sub sound their best. Utilizing the high-pass filters, you can remove the extreme low bass from your full-range speakers, so they'll play more efficiently. You can adjust the subwoofer channel's low-pass filter and bass boost to get just the right bass tone. This five channel amplifier comes with a remote bass knob and cable, providing the ability to control the bass from the dash. In addition, the SK-M9005D utilizes a Molex Connector for the speaker outputs allowing for an easier installation.
