Please excuse my ignorance but until last week this amp was fine but now every time I press a command button on my Tosh DVD I keep getting a loud crack from my right front speaker.Also when I use the test tone there is a loud crack not only when the test tone is first activated but also just before the centre and rear right speakers.I've checked all wiring but cant help thinking that I'm just doing something wrong somewhere and its not the amps fault.I've even swapped speakers and cables but to no avail.Any suggestions gratefully received.
