bad luck?

THIS IS ONE TERRIBLE AMPLIFIER.MAYBE IT WAS JUST DEFECTIVE FROM THE START.THE SOUND IT PRODUCES IS POOR AT BEST.ALSO IT RATTLES INSIDE.MAYBE UPS DROPPED OR SOMETHING.ALSO I THINK ITS SHORTING OUT AS IT CREATES A CRACKLING IN CHANNEL 4.I ALSO HATE THE DIALS AT THE BOTTOM.

Great xover options for $150!!!

You would be hard pressed to find an amp for $150 that has these crossover options. This one is great for an active component setup. I'm giving everything above 3000Hz to my tweeters and 80Hz-3500Hz goes to the mids. If your head unit has separate front/back RCA outs, then you can use your fader to balance the output between your tweets and mids. You could also run a component set with a passive xover on channels 1/2 and set channels 3/4 to bandpass between 80Hz and 300hz for a set of mid-bass drivers. If your head unit has separate front/back RCA outs, then you can use your fader to balance the output between your tweets and mids.

It comes with a detailed birthsheet. You know exactly how much power it puts out, which is more than rated. I was not too crazy about the big "X Thunder" logo on the top. It looks a little gaudy to me, but it's going under the front seat so who cares. All-in-all this is a great little amp with great features at a low low price.
