Hi there,
First do a test on another device like a cell phone or walk man. You can also test the speaker with a battery. A sub with a different Ohms can also damage the amp. a 4 ohm speaker will drop lower than 4 ohms.the average is 4 ohms because the impedance goes up and down depending on frequency.
So if you say 4 ohms is the max. you don't want the 4 ohm speaker going lower and stressing/damaging the amp. Also have a look at 'impedance curve' and you will see the line changes from whatever ohm is in the specifications a 4 ohm speaker might drop well down to 2 ohms and some people would either destroy their amp faster, or cause their protect mode to turn on, or cause their protect mode to grow more and more sensitive until the receiver doesn't want to work with 8 ohm speakers ever again.

Look for a wire strand or solder splash on any circuit boards or connections that might be 'almost' shorting out anything. Next, if there are any metal screws with very pointy tips (like sheet metal screws) that might be just a smidge too long and clip the very tip off so that it can't possibly short a frame to a component.
The idea is to find any reason why electricity might be bleeding over into another area of a circuit board that uses capacitors where a charge could build up causing the symptom you are describing.
