i have had my system out of my car for a while but i hooked it all back up (07 camry)

i have a bad engine whine coming through my head unit . I also have a clarion preamp/eq that has a real bad ground noise also that i believe is just boosting the headunit noise. the only thing different from the time it was last hooked up is a 1/0 big 3. could that cause ground noise?

i am using the power from from the wires that came from the cigarete lighter adapter and the ground from my factory amp ground location.

when i took power str8 from the battery through a jumper cable the ground noise was considerably lower but still there

i have tried using different ground spots and i have tried grounding rca's along with trading them all out.when i ran rca from my other car str8 to the amp no noise. when i ran it to the eq noise.

any suggestion what i can try?

Where is your EQ grounded at? Ground it at the same place as the head unit, or try grounding it as the same place as your amp.

Try grounds first. Those are used as a last resort.

Give me a schematic of what all you have. List it out from source back to the speakers.
