I recently reinstalled my system and at first all was well. But now I'm hearing engine noise. I have the power and remote on one side and everything else on the otherside. My grounds are to the rear struts. Any ideas of waht else to check?

 

Bad ground would be my first guess....struts arent a good place for a ground.

try grounding it to the chassis itself. sand off any paint at the contact point to ensure a nice ground.
