About this item

Product details

Optimize your sound on every road trip or errand run with the Crunch 12-Inch 800-Watt Subwoofer and Audio Stereo Amplifier. This package comes with (2) 12inch 800 Watt 4 Ohm Car Subwoofer Speakers and (1) Audio Stereo Amplifier. The 12-inch cart stereo speaker pumps out 800 watts of MAX power and 400 watts RMS power with a 4-ohm impedance creating powerful, quality sound to accompany you on your car adventures. The vented aluminum former holds a 2-inch voice coil and allows heat to be exchanged resulting in less heat distortion. Designed with a heavy-duty, powder-coated steel frame, this sub allows back venting for increased power handling and reliability. The Crunch POWERX amplifier incorporates full Class A/B technology in stereo and 4-channel amplifiers along with Class D in the mono. Class A/B sounds better, but the PC boards require a bit more space that in other circuit topologies.

I feel like they could kick harder. Also, the pack includes a monoblock amp to dual voice coil subs. Fine if you wire the speakers in paralell/series, but you can't wire each voice coil independently as the amp doesnt have enough channels. You may also want a capacitor if your lights dim
