Hi, Any solutions to this hissing problem. I have the same exact problem after the JL xd600/6 install, i hear the noticeably hiss from my mids even when the HU is off ( ignition on ) or even when HU is playing CD at volume zero. I don't hear the Hiss if i disconnect the RCA's. Mine is HIFI system on E92 2009 model. I even hear the hiss even after lowering the input gain, but the hiss sound is little less but still noticeable.
