In my experience, bad capacitors have caused noise.

It’s only the left rear channel on the amp so it’s definitely the amp.

is it hard find which one it is?

If it's a capacitor, and it's blown it would be easy to find as it would be swollen. Take a look at the board and look for any black spots or blown capacitors.

Agreed, board and caps look fine. Could be a soldering issue, which you'd have to flip the board to check. First though, have you double checked power and grounds? The amp may pickup interference in the power or ground. What amp is it? Cheap amps sometimes are just cheap amps

Yeah the power and grounds seem fine plus it’s just the one channel that is doing it every other one is fine

it’s a pioneer gm-9705 had it for almost 2 years now and it just started doing it

Check your speaker terminals and wires for corrosion. Flip the RCA left/right and see if the white noise flips sides.
