I have a 08 ISF with ML/NAV, recently I have noticed that the rear door mids are not playing( tried swapping around the surround and the ASL) still only tweeters and woofers only play...has anyone else noticed this?.....the only thing that I have done is tapped the sub wires, disconnected the ML sub( which is rattling), and installed a sub.... ( did not really notice if they was playing before then).....could me disconnecting the ML sub some how effect the rear door mids?? seems unlikely to me but thought Id ask anyway
