Problem solved, was the ground

Well it fixed it once, however it came back. I tightened up the ground and that worked but its back. The ground isnt in a ring terminal its just the wire wrapped around the bolt and then bolted into the frame under the driver's seat. However theres also a little static comming from the passenger side tweeter. Im not sure if its because the power wire and the rcas are so close or if the ground just isnt making a good connection. Anyone have an idea? The rcas and power wire are ran separate ways but at one point where they are comming from under the carpet they are about 2 inches from each other. So im not sure if its that or the ground, any input?
