Most likely the ground from the deck, make sure it's grounded to metal and not to the car's harness if your going to try and fix it.
so how many mids/highs does he have? he has the stock BOSE system and other speakers on an amp? is the noise a popping sound?are the gains all the way up?
oh, factory bose head unit, then it wouldn't be the ground from the deck making noise but it does sound like a ground problem. Maybe it's coming from the loc, maybe try grounding the loc to metal.
