Okay let me start this from the beginning I have just purchased a new sub and amp (sundown sa 12 and a mb quart onyx 1600.1) I put it all in no issues what so ever. Have it playing for a week or so and then I start to develop a ground loop issue, small at the time. I research and find fixes if that what you want to call it by grounding the rca preouts to the chassis of the deck so I do that and it reduces a little. Then the next day I begin to get loud pops, static and scratchiness, so bad to a point where I cannot even plug in my rcas to my amps. I am running a pioneer deck Rockford 4 channel and the mb quart. I noticed today that when I plug rcas in it sends my Rockford in and out of protect, which may cause the pops maybe? I don’t know anymore ive changed grounds and everything and am wondering if I spend money on rca cables that it will fix this issue.
Any help would be greatly appreciated
thank you
