[QUOTE="ThxOne, post: 8922793, member: 675210"] That is odd. I am wondering why you have rear speaker wire colors going in to the LC7i into the [U]Main Input[/U] and front color speaker wires going in to [U]Channel 2[/U]? Can't the LC7i sum just the main input to all 3 RCA outputs? If so, I would disconnect the speaker wires you have going into the input of Channel 2 on the LC7i and see if it fixes the crackling. There may be some crosstalk in the LOC. Also, try the white and grey wires into the main input and see if they alone will eliminate the crackling. I am not sure how you have that 9 wire connected or to what to get signal but typically on most installs the white and grey are front left and right and the green and purple wires are the left and right rear.
