you can figure this out by process of elimination ...
1 take the radio out disconnect all speakers and leave the power hooked up red/yellow/black
2 one at a time hook up one speaker start with left front white / white-black turn sound up . all good ? tape it back up leave it connected . Turn volume down
3 move on to right front grey/grey-black do the same thing . still work ? keep going till your problem comes back
Note if you start with the first speaker (left front) and sound clips , disconnect and move to the right front and start there . You can do one at a time also , just make sure no wires coming from the radio touch ground(anything metal )
Hard to say, depends on the stereo; Im still betting the input is being over driven. Been working in the business for many years and I see that a lot.
If he turns down the volume and the problem goes away then he will know. Quick and easier to check than going back over the install. And obviously if it does continue then he knows something else is wrong. At that point I would suspect a problem with the stereo, or the way it was installed. I had a problem where I installed a new radio in an old car that used the chassis for the return, blew the final, but the stereo still worked... sort of.
