I have a noise floor problem that is totally driving me insane. On low listening volumes there is no noise but as volume increases so does the hiss. It doesn't matter if the car is on or off it is always there. Depending on the recording it may be more or less noticable but never goes away.

With the Gains set properly or even set low it doesn't go away.

Right now all I have in the car is
Alpine CDA-9853 - Ground to vehicle chasis
stinger hyper series RCA's - run along opposite side as power
Xtant 404m - Ground to Vehicle Chasis
Infinity reference 6010 components (hate them but thats another story all together)

I have the Crossovers in the hatch with two lengthes of 16g speaker cable to the doors where components are in factory locations.

Could the fact that the 9853 only has 2v preouts be a contributing factor?

I've redone my grounds in various other locations to no avail.

This is driving me totally insane.

 

Try a different cd player first and see if the noise is still present.
