The height is only 2.8 inches! We utilize an advanced 6x8 inch subwoofer and the enclosure is only 7.68 x 10.24 inches which means their is is almost no wasted space. When you pick up the subwoofer you can immediately feel how solid it is weighing in at just under 10 lbs. This is a true all in one subwoofer solution that combines a high quality subwoofer inside a sturdy Aluminum enclosure with the amplifier built in. We added high level inputs so you can install this to an aftermarket or a factory stereo system. The smart turn-on circuit will sense that an audio signal is present and turn on the amplifier. When you turn off your music signal the amplifier built into this subwoofer system will automatically turn itself off. Something else we did to make installation quick and easy is we put all the inputs and outputs on one side. This makes wiring neater and easier. Our competitor’s models are more challenging to install. The RW68CA has 400 watts of peak power and 100 watts RMS. This has great controls so you can adjust the sound to your liking. It has a level control for the volume and subsonic filter to filter out the really low frequencies which the human ear cannot hear. This also has a low pass crossover filter, phase control, input sensitivity, and bass boost. Included is a remote bass knob, and mounting hardware.
