hissing from speakers

[David Robertson]

i have a cd head unit, 5 channel amp, sub, front 6 inch 2 ways, and 6x9 4 ways.i get an annoying hissing from my speakers on lower volume. no alternator noise i think. i also think i can hear clikcing when the hazard lights are on.

what could be the cause of my problems? any tips or solutions?

thanks good people!

is your headunit any chance a pioneer?

Makes and models of equipment?

Typically an issue with gains being too high.

Grounding the head unit ground wire to chassis instead of the harness can help as well.
