Hello! I installed a new stereo from China, and I started experiencing noise from the stereo while the car is on. It gets louder as I accelerate, too.
Is there anyone that has a similar problem that could help me?

I am aware that there are similar threads but since I am not very experienced with cars, I'd love if someone could explain exactly what I should attempt to do, which cables to re-wire etc. Maybe someone has a simpler solution even.

The stereo us probably pivking up electrical interference

Did the old unit pick it?
When people say a Chinese unit it does sometimes leave a questionable quality/reliability questions

Hi!

You should try grounding alternator frame directly to car body. If that won't help, head unit is faulty.

This sort of thing used to happen a lot on old cars. Cars before electronic ignition systems became the norm.


There were things sold suppression capacitors that you fitted in-line with the ignition/alternator & that stopped the whine. I don't know if theses are still available but the most likely reason is a cheap stereo rather than a fault with the car.

Sorry about the super-late reply. I know this did not happen with the old stereo. I had to convert the old cable from the car to a new one with clips. Any more information you can give me? I am not very good with this so I am not entirely sure what to do.

This is what was done in the old days

The bit about generator/alternator would be the only relevant part as dynamos, points and coils are gone.
It's possible that the new stereo is more sensitive to interference.
