Grounding LOC?

[tat2bass 10+ year member]

Does grounding the RCA's work when using a line output converter? My subs will hit every time my engine idles. Once I start driving and get above the idling rpm range it quits. I've sanded the hell out of my grounds and they are more than abundant. My last resort is to ground the RCAs or run an inline ground loop filter which I don't want to do. But I don't want to take apart my whole dash to get to my loc to ground the RCAs if it doesn't work on LOCs anyways. I've already regrounded the head unit with 8 gauge OFC.

I have a 2013 ford cmax with the Sony system if it makes any difference. No stock sub setup. Running a Boston gt 2300 on a Boston spg555. Power and ground is OFC 0 gauge and 4 gauge to the inputs. Battery in the rear so no crossing of cables going on

That's not an RCA ground problem. Can you measure the power voltage at the amp while a helper revs the engine? Nobody has replied because this is really a wierd problem.

I know. It's weird too cause it doesn't do it after the engine is warmed up. After 10-15 minutes it won't do it when it idles. Try an inline filter and see what that does after I test the voltage.

Active Noise Cancellation. Dirty SOB. Apparently it is stock on the CMax but isn't listed anywhere. I disconnected the 3 mic's and everything works perfect and noise free now
