Hi guys.
As stated above,sometimes my dashboard speaker got hissing sound.
It was like wrong radio frequency but it only happens around 10 seconds.

what is your config/wiring? (amp/comp/hu etc)

HU>Speaker bro.no amp,etc.

check head unit grounding wiring.. maybe extend or split another ground to chassis.

if ur speaker got crossover, try to move it to other place with less car wiring..

Hmm..head unit grounding eh..black color wire right?
So if split,i have to cut and tap to other point la?

No crossover taikor..just normal setup..

yup grounding is black color. you can either reroute the negative ground cable to any solid metal chassis & screw it there or can splice then find another grounding spot. I think the former one work best. btw, have you check ur antenna plug? maybe loose connection can cause humming & hissing. If the above method won't work maybe you need to get a noise suppressor from kedai abang. Gud luck..

You having this problem since you change your HU/speaker? Or was it a stock system?

Thank u for ur reply bro..i'll try to check it later and update here..

Thanks for ur reply also bro..
I'm not sure because last time i only have rear speaker..
And i don't know why i keep thinking about the grounding in engine bay caused the hissing..is it related or not?

Any possibility the hissing from the front speaker itself?
