I have a Zcon 12 on a BC2000. I am unsure on how to set everything properly. I set gains by ear and it has always worked out for me. Now how do I tune everything? I have the power and ground of the lc2i at the battery in back. I have left and right inputs tapped into the rear speakers. There are 3 dials. I don't know where to start. I tried messing with it last night and couldn't get it right. If anyone that has/had this can help me that'd be great. Thanks in advance.
