Speaker Bussing

[charbygt]

I have a Moonsoon system and I am getting a bussing sound from all speakers. I have not modified any electrical components and the low bussing sound is there without the radio even on. When I have the radio on at low volume,(1-2 lights) I can hear some increase with engine noise. Any ideas before I buss out..:banghead

maybe your alt is going out

There might be a loose/bad ground somewhere, if it is increasing with the speed of your vehicle. BTW, buZZing is what your radio is doing, unless it is clearing tables in a restaurant.
