head unit volume control switch?
i installed my head unit in the trunk for various reasons, just running to two 6x9's nothing fancy with no amp. the unit has a remote but has a range of like 4"s! so i cant control the volume from inside the car, i can manually increase it but when i turn the car off and back on it defaults to a level so low i cant hear it over the car. so i was thinking and old school EQ maybe? is there such a thing as a universal car audio remote? the remote is debit card size with a watch battery and no range at all? or some type of volume control knob/switch?
thanks in advance!
