So i wan 2 ask wheater u guys got come across tis kind of problem not?? n how u guys settle it??? Thanks.

Wah... your car become to highend...break can hear sound from ICE...

I have never encountered this type of problem.
Definately it is an installation fault.
Change your installer, he is talking crap.

but i duno how 2 desribe the sound lah! in chinese they call it something like "Fei Chi sound". infact some of my fren install in other places also got tis kind of sound. my fren wan lagi teruk, everytime when he step the acceletor, the sound follow up 2 the speaker.

just as I was told my friends that I want to connect my exhaust to my woofer hahah

1. check ur grounding - dont ground too near battery/engine
2. alternator carbon brush - last time my fren's wira got this sound..then his alternator kong after few days...carbon finish..after put in new carbon then no more this sound
3. spark plug cable leak - old spark plug cable will somehow 'leak' the high voltage to the chassis ground...causing the aeroplane sound
4. HU/amp filter kong

hope this help

wat ever thing u do.. juz don't install the suspressor...

go to a better shop and ask for a proper grounding.. don listen to those fellar giving u stupid excuses... the less knowledge that u know the more they will try 2 bully u..

wat it got 2 do wif preamp??

Most probably it has something to do with the cabling. I've a friend that encountered a similar problem after he has installed high-end XLO cables into his system.

Your RCA cable needs to be checked/shielded or changed. It's picking up all sorts of car noises.

Ya, when they install my amp, the RCA cable they wrap with ikan bakar silver paper(forget wat they call in english). They told me tat tis is 2 avoid any unwanted noise came out from the speaker. But my car also kena.

that silver paper is called aluminium foil. but i never know that got ppl wrap this aluminium foil for amp installation..

u better g0 back 2 that sh0p and sc0ld them up side down.. is there any place we can complaint this kind of ppl?

Bro, how is Amp filter look like? If kong how should we do then?
Btw, is filter same as fuse?

most new hu..this thing is inside the amplifier/hu itself..

but some old HU do come with a little small black box at the 12v line..inside it is a few capacitor to cut off unwanted noise
