Um...try regrounding your head unit...make a new solid ground for it...bare metal.

And I would suggest rather a nut and a bolt for a ground and sand away all paint to clean bare metal

Do you think its the way I connected the power to the amp?

I just connected the wire directly from the battery to the amp. Is this the right way to do it?

I suggest reading the grounding sticky threads at the top of the forum listing. Those threads are there to help with thse sorts of problems since they come up over and over again. Please read them, then come back and ask questions if you don't understand.

you could also have a bad ground within your CD player. Pioneers decks have been notorius for this.

Yes, my cd player might hav a bad ground :(. I just connected all the wires from my factory toyota HU Engine Noise with 640 watt amp - Page 2 -- posted image.

to my new panasonic one.

I asked a friend and they said to test the RCA cables with a mp3 player or something like that. I used a 3.5mm jack to RCA(female) converter, and then used the RCA cables which I used to connect my HU to Amp. I turned on the car and there was no whine!

So do think its my HU ground? Btw: It's a Panasonic CQ-C7300W

ok, I re-grounded my head unit to where my amp was grounded but the noise still comes! ARGH!!!

I have sanded it VERY well, its bare metal.

I used gold plated connectors and a nut and bolt.

Please Help Me!

You can also try grounding the outer portion of the rca's at the deck/amp.

My ex once told me I have a perfect face for radio.

Did you read the grounding sticky threads? Did you measure your amplifier ground return resistance?
