My stock amplifier is not working that well. Perhaps if any of the 530(E39) owners in this forum have upgraded their audio system and have the stock OEM amplifier to sell, please drop me a PM. Please also quote the part number for me to double check its compatibility. Or alternatively can someone guide me to a shop that can repair it. Appreciate feedbacks.
