Speaker Whine

[Aerton]

Ok so after not having a working radio in my car for almost a year I finally installed a new to me Blaupunkt Madrid 105. I used all the original power wires from the BMW harness. Everything works just fine and I put the car back together. Until I take it for a drive.... as I accelerate the speakers whine along with the RPMs. Any way of testing speaker wires for this cause, filters on the power leads etc. Kindly advise.
Also when I was testing the radio the power antenna was working just fine, turn the radio on and the she goes. But at one point it stopped working, it wont go up. I tested the lead for the antenna and it receives a signal when the radio goes on. The fuse under the hood is ok, is there another fuse by the antenna, or any other ideas as to what I might have screwed up?
Thanks guys....

Pull out your heaunit and connect a test speaker directly to it, not through bmw harness and see what happens. Just throw in on the seat and go for a spin.

Antennas get stuck going up or down sometimes. Give it a little help when it goes up or down.

Yeah, I have speaker whine as well. Bad ground?
Also when I turn on my xenons, they whine even louder.

are you using solid core spark plug wires? cus that will give you a very nice whine!

Well the BMW harness I'm using is the power one not the speakers, the PO had run a thick clear monster style cable and I'm using it. The previous radio did not whine, Dam Sony!!! Can't think what I did different. I'm using different speakers in the back, 5 1/4 midrange speakers Cerwin Vega, I hard wired them and used a baffle so they are not touching or creating a ground.
As for spark plug wire it's a stock wire.

Might be a lousy ground connection of the HU. Or RCAs picking up noise, but that's if you rock an after market amplifier. Try yanking you HU out and throwing a ground to let's say door latch on the body side or any other solid ground. Heck, ground it to the battery if you have a long enough cable. If all fails - it is your head unit that is causing issues.

I was just commenting to a guy at work about my radio issues, he is a fellow car enthusiast but into older American Muscle. I said I should have been a hairdresser as I suck at audio installation....

I will try a ground and a positive from the engine bay right into the cabin for testing purpose. I remember having issues like this with my Jetta but I guess I found the way. Well one more day to trouble shoot I guess.

Thank you for the input guys.
