I hooked up this amp and bridged 2 channels to a 6.5 in. Sub and it sounds really good, nice bass. It's probably 80-100watts rms bridged. The other 2 channels are hooked up to 4 , 6.5 kicker door speakers, they sound really good also. I was impressed at how good it sounds. I drive about 25-30 min to work everyday with the music cranked up and the little amp handles everything pretty good, no over heating. So I recommend this amp to anybody on a budget and wanting to enhance the sound in their car.

Good Amp!

The amp is well worth the price for the power it produces. Its very convenient to ise all 4 channels or switch to mono block, and even a bridged 2 channel system.
