Another Ground Loop/RCA/LOC thread

[SpeedEuphoria 10+ year member]

Hey all was well for a period and now I have this issue where when the radio is off, amp is ON the sub goes crazy.

I found this:Line out converter Ground Loop Issue? - Tech Support - Stinger Electronics

Which is the same issue as I thought is could be the LOC

For some reason this car does not have a "radio" fuse in the fuse box only a relay. The manual and pic on the fuse box is totally screwy as it says there is a radio fuse but its not present prob due to it having the "upgraded" stereo option.

What I'm wondering is since I hear this noise only when the radio is off and amp on, am i still getting some distortion when the radio is actually running?

I tried 3 diff RCA's none are near anything I promise, tried grounding the LOC, ect..

Pretty sure that stinger post is correct and I just have to dig deeper for radio power wire since leaving the radio on as said in that link still leaves me with the sub going for a sec when I shut the car off.
