Hello mate, it was me who did the amp install. There is no amp in the BMW Compact. Unless it was chosen on option. The factory HU was AMP'd like they are nowadays.
I did notice, however, that there was RCA leads in the car as standard. But that may of been for the audio for the CD changer! It looked like mine had been removed. I fitted an amp and a 12" sub in there. Also I have some Focal co-ax's (13cm) to go in the rear and looking at some 13cm components for the front!
The amp and sub is JBL and the HU is Clarion (when I get it repaired!!)
