It is designed with top mounted rotary controls and has an illuminated panel to make it easily viewable regardless of where it is placed in the car. The KS-AR7004 can be externally bridged making it possible to use it along with multiple amplifiers for even more power. It offers numerous controls including variable speaker level and bass boost controls as well as variable high pass, variable low pass, and subsonic filters. It also includes protected anti-pop circuitry for long-lasting performace. The amplifier is the predecessor to JVC's digital KS-AR8004D from it's 2009 Arsenal AR8000 series.
