Excellent for the money running 50 watt RMS to my pioneer 6" coaxial rears, and 50 watt RMS to the my pioneer 4" w/ tweeters to the front. They say the 5th channel is only 225 watt RMS @ 4oms, well I got it to 300 watts @ 4ohms to match my infinity 12" sub. It pounds hard did about a 2 hour road tip running full bore amp never shut off once and absolutely no clipping, it was warm to the touch but not hot. I do have it mounted to wood then to my back seat so it does have good air flow. For a $130 bucks really hard to beat. Hopefully it lasts a few years. I recommend it. Like with all amps make sure you tune it properly with a volt meter or other device and this one will be good to you
