do you have an external amplifier? If not, are you cranking your volume to the max? Headunits alone can't provide much power, and often have less than desirable s/n ratios, meaning more static or hiss at higher volumes.
If you ARE using an external amp, are your RCA cables of HIGH quality and ran away from power/ground wires?
