hey... i have a pretty nice stereo... i have a rockford fosgate 201s amp running my 6 by 9'*... for some odd reason i hear a whining sound that alters based on acceleration... so its engine whine? i was told to try new and improved RCA cables, i did so and the whine still exist! does anyone know how i can stop this! ITS SO ANNOYING!

its most likely alternator interference with your wires

are your power wires and RCA run on opposite sides of the car? if not they should be.

I would have to look into more ways to fix that because I forget.

cuz you ran your RCA'* and power wires on the same side of the car...

i did RCA'* on the passenger side and power on the driver side

i would look into a ground loop isolator

i have my RCA'* on passenger side, my cable wire on my driverside! i have a 4 guage power that is split by a 4 way 8 guage distribution block... the wires are kinda messy in the trunk and rca'* are near the power in the trunk only.... but what are ground loop isolators? good investment? better?

Try a new ground location, and clean it down and use di-lectric grease.

MMMmmmmmmmmm dielectric... my best friend on my bonne

GROUND LOOP ISOLATOR did the ol' trick.... and i really had to isolate and organize the B+ wire from the RCA'*

could you let me know where you installed the ground loop isolator? I'm having the same problems, and will start tearing apart the sse tomorrow to fix the annoying sound

all you need to do is reground your amp take some sand paper and take you grounding area down to metal that will save you a couple of bucks
