Is mine aeroplane sound?

[ebayer]

Hi, I have been reading a lot about this aeroplane sound and I read it has mostly to do with grounding, the RCA cable being too near the power cable and numerous other causes.

My problem:

I initially installed 2-way components and 4-channel amplifier with stock HU. Everything was fine.

I then installed a subwoofer and use the 2-channels from the amp to drive the sub and I removed my rear speakers. Now, when the engine is off, the sound is great but when the engine is running and I increase volume, I hear in my left ear some *krrk krrk* sound (very soft) and it totally ruins the music from the left side.

Can anyone help? I am not even sure if that's the 'aeroplane' sound everyone talks about.

aeroplane sounds means the u can hear the sound getting louder when u step on the accelerator. krrk krrk doesnt sound aeroplane to me. More like its ur speaker (especially if only one side involved)

can switch around the amp output to the speaker (left to right) and see if the sound comes out from left or right speaker, then only will know speaker problem or something else.

normally it should be the crossover putting near some sort of power source that carry some signal and affected the crossover. Try to move your crossover to somewhere else

Actually the feeling in my ear is more of like when you are going up or down the KL Tower lift or when the plane is taking off, and the pressure in your ear is not equalised and you have to swallow to equalise the pressure. I don't know whether there is something wrong with my hearing or the sound system....:stupid:

check your wiring properly, with any luck it could just be a loose rca cable..

first... does it increase with your volume or when you step on the accelerator? recently there is a case happen to my friend... similar sound... and the problem was with the HU fuse... which happen to "not functioning well" changed the fuse and all went back ok already...

cheers...
