Ground Noise or Something

[rmzsuzuki89 10+ year member]

I've been trying to trouble shoot my hissing noise for a while now and don't know where else to look. When the sub amp is hooked up, the subs have a slight crackle, and the tweeters hiss. But when I unhook the remote to the sub amp the highs are fine. I've moved all of the grounds in the back around to a few different places. I've also tried grounding the head unit, and checked the rcas and tried a different set of rcas.Also added a relay. Grounding the hu kinda lessened the hissing in the highs, but not too much. I don't really know where else to check. I was thinking about just getting a new hu to see if mine is taking a ****...Any advice?

You should have all your grounds to the same place.

^^^ what he said, run all your ground to the same place.

Best place is to a frame bolt

All is grounded at the back bank, which is also grounded to the frame and to the front batt which is also grounded to the frame. Should I move them to the same place on the buss bar?

And the hu is an Alpine iDA-X100 that's a couple years old.
