Hi guys,

Past few days i noticed the below from my car audio system. any idea what could be the reasons? solution ? expensive to fix ? can i diy checking my self to save money?

- front left speaker got this low "bobobo" sound even the volume is zero (if i switch off the audio, the sound gone meaning it's audio issue, not others).

- got a very low aeroplane sound when car slowing down.

Is this happened just recently or it was there all along?

Do you have separate amplifier or just radio itself?

Does the sound change when you play with your gas pedal?

audio cable kena ground for left front speaker
aeroplane sound need supressor on power cable

suggest just change to new set of audio.

got original separate amplifier i believe

i think may be lately.

the aeroplane sound only audible when i slow down.

Need a ground loop isolator.

why previously dont have one, suddenly happened.

Usually has LNF Low Noise Filter. Probably gone bad.

earth not enough also can happen

u want to spend modify or just fix it
may i know

hi bro,

I just wanna fix it with minimal cost, no money liao.

Finally found the problems:

Humming noise: the 12 years stock head unit mother board spoiled.

3 speakers no bass only low sound = all 3 speakers voice coil jammed, cannot vibrate anymore.

Solutin:
Changed to Tomahawk Android Player + new Mohawk speaker.

I am too hurry, should have shop around more, this particular shop charged me higher than market price. But learned a lesson for future.
