I have a 96 E320 (W210 body) and am trying to figure out where the amp for the sound system is (or is there one?). I have the Bose system which I believe is a 6 speaker system. Looking at the colors of the wires connected to the speakers, they don't match the colors coming off the back of the head unit. Therefore I presume there is an amp somewhere in the car. So far I ripped apart the trunk and only found the gas tank and phone system transceiver. Can anyone help out? Thanks in advance.
