Summary: I bought this to replace my 500 watt memphis amp because i wanted more power. I hooked it up and it wouldnt get near as loud as the memphis anp did. So I put it on a smd amp dyno that a local car audio shop has to see how much power it really put out and it only put out 245 watts at 2 ohms. The Memphis amp put out 536 watts on the same amp dyno. I requested a replacement because I figured it was just a defective one. The replacement only put out 215 watts.
Summary: Unit was failed right out of the box. Right channel had only 1/2 cycle so output was highly distorted. Looking inside I could see a shoddy patch in the right side electronics (I'm an electrical engineer) where someone had tried to solder a resistor to the top of the board where the previous component had been clipped out. This was supposed to be a new unit I had purchased.
Summary: Great deal. I've been into car audio for almost 20 years. I can't remember ever getting a decent sounding amp for 70 bucks. That being said, it's definitely NOT 3000 watts, but I expected that when I bought it. I bet it's nearly 1000 at 2ohms....
Summary: I've had this amp about a month and a half now and I have it hooked with 4 gauge wires and 2-2 ohm peak, 12" Polk audio subwoofers and I have not had a single problem with it, I turn up my radio not even half way up and it pounds so hard you can barely hear yourself think haha. Don't turn the bass booster up though, it started hurting my ears that's how strong it was. So I turned it down a notch and it's PERFECT.
