I recently purchased a set of bsw midranges for my 2001 540i sport with premium sound system. When listening to a cd or the radio they sound great. After getting them installed my dice unit for my ipod will only play out of the speakers on the left side of the car. But when i switch to play a cd or the radio sound comes out of all the speakers. Can anyone help?

something is wrong with the dice connection. contact the dealer who sold you the unit.
