sounds like a cracked trace or solder joint, you should try to get this taken care of soon, those pops can really mess with your speakers (and ears)
you could try opening the amplifier, turning it on, and while its on, pushing on each of the circuit boards with a sharpie, to see if you can isolate which PCB has the problem. you can also use the sharpie to wiggle individual components to see if you can isolate a specific device. once you isolate the problem, you can either look very closely at the board to see if you an see a cracked solder joint. if you isolated a single component reflow the solder on that component, but still look at the whole board, sometimes there are more than one. You can also just reflow the solder on the whole board. the latter option is a little labor intensive, but it can actually save you some time
