Hello, have a question about the Premium Sound Package 2. As I understand it, it consists of 4 speakers and an amplifier. The yellow boxes are for the doors and are connected to the additional amplifier. The gray ones are for the rear and are connected directly to the radio, right? Which are the yellow speakers: Premium speaker set 08A60-SMR600A (double cone) or Premium speaker set 08A60-SMR600B (2 ways) On the picture on the internet (Premium Bass Sound System 08A54-SMR kit2, would say that this is from the Civic price list only with slightly different name) are funnyly pictured by each one. Maybe someone else has got the package with the part numbers and could post them. Background, Honda has so many different systems with the same name and no one knows. Did the Premium Bass Sound System from the normal Civic built in me, which consists only of the gray boxes with the amplifier (sounds neija, money would have saved me). How did you have the amplifier in conjunction with the original radio leveled greeting and thanks Olli?
