Feed your undernourished sound system a dose of Kicker power and watch it spring to life! The built-like-a-tank ZR120 punches out 30 watts x 2 channels to your full-range speakers, or up to 180 watts (at 2 ohms) to a subwoofer in bridged mode. Go ahead — load this amp down! The ZR120's unregulated power supply allows it to crank out big power at lower impedances (as low as 1-ohm stereo or 2-ohms mono) that would fry a lesser amp.

The automatic bridging feature makes stereo, bridged mono, or simultaneous stereo/mono three-channel operation easy and free of switches. A quality assurance certificate comes with the amp to prove it meets and exceeds Kicker's strenuous tests for power and performance. You'll be getting one-of-a-kind, not one-of-a-batch!

Space saving powerhouse

Written By Raptor660, Eaton Rapids, MI on Tuesday, September 21, 2010

Ive owned lots of big amps So i thought maybe use it to power interior speakers...to test this amp i hooked it up to my buddies 2 10" 1000w HX2's and it flexed em good! was very surprized. I would imagine this amp would be perfect to power 2 Kicker Comps, CVR's, P1's, P2's, ect.
