Hissing through speakers with new headunit.

[Benjamins]

I installed a Kenwood DNX5120, i ran the speaker wires to the headunit to use the kenwood amp. when i connected the amp-turn on interface on the wiring harness, the hissing starts. it happens through, cd, ipod, radio. the hissing does not affect the subwoofer. and i tried different grounds several times. and i even got it working without grounding it, i really dont see how it worked.

if anyone can help me with this terrible his it would help me alot.

try, grounding youre H/U to bare metal, ground the chassis of the H/U and the ground wire on the wire harness to the body ground, allong with the vehicles factory ground wire.. then if there is still a his, try grounding the outter shilds of you're RCA's...

if none of that works, try replaceing the H/U and or AMP...
