I have just bought a new Pontiac Wave sedan which is identicle to the Chev Aveo sedan. Have mounted the 700 under the rear parcel shelf and have run #10s straight from the battery to the radio.(Positive and negative) Have also installed Kenwood's chokes on the lines as come in their extension kit and guess what, I have alternaor whine. Not loud so that it gets out on broadcast but we hear it in the car. Since the whine is getting into aftermarket equipment and not GMs factory radio------not their problem. What have others used as good filters for alternator whine?
