With the Kenwood KAC-PS704 you create a powerful audio system in your car. This 4 channel amplifier has a maximum power of 1000 watts. If you connect a subwoofer, the low-pass filter ensures that only the low frequencies are transmitted. This makes the bass sound pure and undistorted. For a deep bass you turn on the Bass Boost function. With this you emphasize the low tones. The aluminum design has a built-in cooling system. This ensures that the amplifier does not overheat.
