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?</p></blockquote><p></p>
