I know it's there, has anyone figured out how to get rid of it yet?

At low volume the stereo has a weak hiss in it. I have had it in both my SS/sc's with the pioneer 7 speaker system. I have currently replaced the amp, speakers, sub, and installed a RF 360.1 for RCA interface. The hiss is obviously from the Stock Head unit. (I grabbed high inputs from after the stock amp and at the headunit and have the same hiss)

Do I need to run a new ground to the stock radio?

I will eventually be changing out the Head unit, but $1500+ is not money I have right now. and the hiss is limiting my output/volume. (I'm loud enough to hear over the windows down at 90, but know more is there) I just have it set so that the hiss is as minimal as possible at min volume. The audio itself is clear, just don't like the factory hiss.

 

hmm can you get the hiss out using the oem interface setup on the 360?

 

nope, I've run it 5 times and it's always there. Everything else with the 360 is great though.

 

damn dont know what to say im stumped.... usually a new ground helps aftermarket HUs and aftermarket pioneers have grounding issues with the rcas but stock... no idea there

 

is the stock headunit really a pioneer? (or just the rest of the system?) if it is maybe I should reground it too...
