Alright I know this is the basics but I've been trying to figure out why I have feedback coming from my head unit. It's the annoying alternator feedback that gets worse as I accelerate more. I added a few of the magnetic noise cancel clips around the alternator wire, power wire, and the power wire to my head unit but it only made it a little better. It may just be the cheap unit but Idk. The unit is a dual double din touch screen from Walmart I wanted something cheap with bluetooth until I decided what good deck I wanted to go with

So it being a dual headunit is not helping matters, but maybe we can try and make it better.
Are your speakers going through an amp, or just the deck? '

If all your speakers that are making the noise, are going through an external amp. I would first check your ground on the amp, keep it short as possible and make sure it's connected to a clean piece of metal.
Then I would make sure the remote turn on wire, and the RCAs are not laying right next to each other. Make sure you also are using a good quality RCA.

If the speakers that are making the noise are connected directly to the deck, options are more limited.
You could try making your ground a little better. Try connecting it directly to a clean piece of metal. But other than that, there might not be much you can do.

hmm, if the noise is coming through the speakers not attached to the amp.
I don't think there will be much you can do, besides trying to get a better ground. But I have a feeling since the deck itself is not the best quality it could be the cause of the noise.

I connected the ground to the ground wire on the deck ima try to upgrade to a better deck when I get home
