my nak radio in my SC is just making this skipping sound like a CD skipping but it does that when i play the radio so its not the cd player and i can hear the radio music but its just skipping sounding- and no sound comes out of the rear speakers. sound only comes out of the front speakers. does any one know what this could be?????

 

its the amp in the trunk under the changer.it has a short circuit protector that cuts out when water shorting the amp. it may be taking on some water. there are 5 leak places for the trunk to get water in the quarterpanel. 2 overflow tubes. the trunk lip gasket, the right tailite gasket and the airflow box under the amp whixch has a gasket that can let wqatewr in the quarterpanel. check trunk below amp for water.
