Whining Noise, I have tried everything

[RCwhat 10+ year member]

here's a bright idea, how about you grab a portable cd player/mp3 player and get a headphone to rca adapter and hook it up to the amp and see if it still whines.......

HA wow your awesome RCWhat. brb i'm going to go try that

AND BEHOLD..... there is NO noise/alt whine when using a portable CD player as the RCA connection instead of the deck! awesome. So now it's down to either the RCA's or the Deck as the prob. I'm borrowing some $80 RCA's(never heard of the brand) from a friend tommorow and his alpine deck, then i'll know for sure ;-)

good to hear some progress, keep us posted on the final verdict.

I had a similar problem. Get a new head unit. That should solve everything.

I'm having the same problem with my pioneer, I think I had a ground trace give out as well, but my internal amp inside the HU blew. Now I have the whine and I can hear the laser head moving inside like you're talking about. I think I'm gonna buy one of those power isolators for my HU and see if that helps.

I fixed my problem! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I made my own low pass filter using a capacitor and inductor. like shown here:

Just look at the woofer part and replace the woofer with the power wires on going to the cd player. It's basically what a power filter does, I think they still sell them at radio shack, but I had the cap. and inductor lying around so I just threw it on there to see if it worked, and I think it did, but I also did what i suggested below at the same time, so it could have been either one.

Also, before you buy anything, try taking a couple pieces of small gauge wire and connect it to the outter barrel of the RCAs. then connect it to ground. I attached mine to a screw on the back of the cd player. (shoulda taken a pic of it while I was in there.)

However, I still have my stock front speakers that i can fade in, and those don't have any alt whine/noise, just anything connected with the RCA's. just another piece of info.

 

[jacko 10+ year member]

The problem is the deck. Oh well at least it's warrented still.

 

[jrz126 10+ year member]

Did you try my suggestions? (especally the rca grounding?), well I guess it doesnt matter if its still warrentied

I have same experience on all Nissan Cars, no matter with Alpine/Panasonic, once I add a amp. the whinning noise will come with the generator.

Now I have another founding that: New Pioneer is worse than old Pioneers.

I take off my olf Pioneer KEH-8650 to brand new DEH-860MP on my Hyundai car.

The old 8650 works well with my a/d/s amp. but new 860MP come out same noise after 2nd try starting the engine. Everything is the same, just swap the HU. Now I wonder new HU with RCAs come with a small connector, should be worse than old HU RCAs come directly from the MLB board.

The other suspect is that I hit speaker + & - together without a care before the nosie coming out. Anybody can help to explain why this short on speaker will impact the RCA noise??? I wonder.

Maybe like you said should I return to fix? I love this HU, it looks cool.

And the iPod adap CD-IB100 is on the way back from Cruthfield

Or I have to wait for Apline 9855 //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

I order my 860MP on Hyaudio but it's said on web that new HU should be test before install, any scratch by install will cause on return. Is it real?

If I can not be refund, can I have them send another new one?
