Radio problem

[Vandame]

Hi, the radio on my BM is still a Buziness radio cassette, the sound is ok but not very loud, i checked in the trunk, i don't see an amplifier, only a CD changer , is there an amplifier somewhere for the radio ??

It’s likely that your car’s audio amp is in the head unit. While all E46s sold in the US have a separate amp, most E46s sold outside the US don’t have a separate amp unless the car has the Harmon/Kardon audio system.
