I replaced my OEM stereo in my 2001 RAV4 with an HD radio (Dual XHD6425) about a year ago. Then I noticed my RAV seemed to have turned into a turbo-charged vehicle because of the noise coming from my speakers when I accelerated (it took me a while to figure out what it was, I thought it really was my engine since the pitch varied with engine rpm). Some on line investigation yielded the source of the problem–alternator noise was being picked up via the new stereo’s 12V power input. I guess it is a common problem with more sensitive amplifiers, and also if you don’t have a really solid ground to the vehicle frame. I installed this filter in series with the 12V supply to the receiver, into the adapter wiring harness supplied with the new stereo (I soldered the connections although a decent crimp job should do just as well). I also added a tap wire off the ground wire in the harness so that I could ground the stereo in close proximity, instead of relying on the vehicle wiring. The alternator whine noise is completely gone now.
This filter is larger than I expected, about 1″ diameter, 1.75″ long. I had no problem fitting it behind the new stereo, but others may have less available space.

It seems to work fine enough. I have one on each channel. Still have some line noise on my Kia Sportage while it’s running. I also have the antenna suppressor, which only helps a bit more. Seems to be a Sportage problem, as the OEM stereo whined on am. I will say that these “cleaned” up the sound. Not worth more than 8 bucks.

I misdiagnosed the whine in my speakers as interference from the alternator (which this product would resolve). Instead, my noise issue was caused by a ground loop which requires a ground loop isolator to resolve. As such, I can’t comment on the effectiveness of this product, but can suggest you correctly identify your issue before buying this and not a GLI.

2006 Toyota RAV4
We have a portable dvd player connected to the cigarette lighter dc power source and audio output through the stereo’s aux input (1/8″ headphone jack both in the center console). Before installing the filter, there was a whine that was synchronized with the rev of the engine.
The filter solved the problem without using the optional ground making this one simple install.
If you’re experiencing ground loop noise, I recommend giving this a shot as a simple, inexpensive solution.
