Whine Through Speakers With Wideband And Radio
I've had a Pioneer AVH-P4300DVD installed for the longest time and never had a problem with feedback through the speakers.
Recently installed an AEM Wideband and whenever both are on, there's a high pitched whine coming through the speakers.
The AEM is grounded to the chassis on the driver's side kick panel and is added to the wiper fuse.
The power wire for the Wideband is going down behind the a pillar and by the amp, etc., down to where the pedals are, and across and behind the center console to the bcm.
If I turn off the radio the whine goes away, but then I got no music.
If I unplug the power wire to my wideband the whine goes away, but then I gots no afr.

I feel like it might have to do something with the amp.. If I turn the source off on the radio, but it's still on, the noise goes away. It's only when the speakers are powered up that the noise comes through.
The power lines for the wideband are by the amp, but there's no bare wires AFAIK.
It's bolted to the bare surface to the right side of your foot, behind the panel on the driver's side.

pioneer has a well known flaw that does this however its much more common with subs installed

Which is..?
I haven't tested if it's actually the RCA's yet, but it kinda doesn't seem like it.
Like I said, only started AFTER wide band install. With wires only from the wide band being close to the amp.

I haven't tried it yet. I hate taking my radio out cause I got a bunch of wires and big boxes jammed up back there. The harness's big box and an HD radio tuner, etc.
It's an Axxess one. I forget which one exactly. For Pioneer without Onstar, even though I got onstar.
To make the whine start, both the radio and wideband have to be on. Unplug the wide band, gone. Turn source off on the radio, gone.

Any luck with this? I've got the same issue (whine through tweeter when powered on) with AEM WB. I'm on stock (Redline 04) stereo with aftermarket subs. If the sensor is unplugged to the WB, goes away. If the Power is unplugged to the WB, goes away. Ground unplugged from WB, goes away. Power to speakers off, goes away. I've tried grounding several places inside the cabin and tapping different fuses, still the same. Getting ready to pass the wires back into the engine bay and see if that helps!
Driving me nuts....

Any luck with this OP? I think a lot of the guys chiming in don't understand that you are not using your RCA outputs on the deck. I have a suggestion, grab power from a different source, I grabbed power for my AEM from the RAP (retained accessory power) fuse at the fuse box. I have never had noise issues, my setup is similar to yours, pioneer AVH-P8400BH, AEM Uego Wideband and an Aeroforce Interceptor and stock amp speakers and sub. Give that a try oh and to get power from the fuse use one of these guys from autozone or similar store it's called add a line or something like that

a lot of times it needs done on Pioneer units...

Grounding is your friend when it comes to car electronics guys. Tapping fuses and adding them is fine, but you have to remember you are putting more power to harnesses that have 18 gauge OEM grounds. Add more. I pigtailed a bolt down ground wire to my stereo wiring harness and attached it to the frame when I did my install. I tapped a new ground the to trunk when I installed my reverse HID's (they clicked the speakers before I did this when they turned on). You never want to run a power wire next to signal wires. If you must then you need some better shielding over the power. Even up my pillar all of my gauges are powered by the OEM boost gauge, but I added an extra ground for each one.
Also, think about an AUX fuse panel for your aftermarket stuff. I am doing this before I add more things that draw power. I will probably add a grounding block at the same time.
