[QUOTE="Moble Enclosurs, post: 7496141, member: 634917"] The LOC has its own gain settings in some cases, so there is an increased sensitivity from the LOC as well. LOCs are known to cause noise problems, and should have its own ground for that reason. Do you have the LOC ground connected to the same ground location as the amplifier or HU? This might be part of the problem. But as everyone has mentioned so far, it is highly likely a ground issue in the system due to the engine noise. Two parts exist...the engine noise/alternator noise and then static noise. The static noise can be controlled by setting the gains properly in most cases due to the mentioned sensitivity increase. You may notice that if an external music player is connected, that this gets louder as well, for the same reason of another low level input being added. Best way to control it is grounding everything independantly, and setting the gains properly. Do not have the LOC gain match all the way up. This increases any noise and distortion from the HU significantly. Hope that helps! [/QUOTE]
