Key Specs
RMS Power: 300 watts (The maximum amount of continuous power the device is able to handle.)
Peak Power Handling: 600 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
Impedance: 4 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
Woofer Size: 12 inches
Woofer Composition: Polypropylene

Sounds great
I have had a lot of sub-woofers over the years. I built a custom designed box for this sub and it shakes the doors off my pick up truck. Love it!!!
