Almost no signal is clean without an osciliscope you'll always have dirty signal, clipping, voltage drop, impedence rise. Yes you get what you pay for but what are you paying? $140? Turn the **** thing down 5v then so it doesn't clip. I know for a fact I got atleast 1200RMS clean out my AP because I clamped it and I tested it on an osciliscope my I have zero clipping and I stayed 13.5v and above. Yeah it does a dirty 1500RMS but it DOES it and it does it reasonably you're not going to blow any speakers off it unless you don't know what you're doing.
