I get this constant airplane-like sound that is in sync with my engine. When I accelerate the sound also accelerate pulak

I think this sound comes when I install AMP

but it was long time ago like 1-2 years already but recently I'm thinking of getting rid of it

The sound is gone when I turn off my head unit

I ask my SC he tell me is the wiring they use for the AMP didn't install properly is it?

I cannot bring back to the same shop already cause the boss and workers all changed but I still have the receipt

But I want to go other place do since the skill of the first shop cause the airplane sound in the first place so I want to avoid going back

Any idea might be other issue that causing this ah?

Or got any shop with better skills / experience one can introduce around Klang / Subang / PJ area?

is this the whine you talking about?



for my case, the sound is only audible when I'm sitting inside the car, and the sound goes away when I turn off my head unit, no whine can be heard from the outside engine though

How thick is ur wiring.. As what some may comment, could be wiring as the main source of your issue.. Are you using a high to low converter?

Does it radio comes with rca output? If not.. they normally use the rca converter which they would tap the speakers wire to create a rca output.. you can Google out what does rca converter looks like

If you dun have a hilo converter or an accessory shop 'crossover', prolly your rca is hugging your power cable. Either parallel next to each other or crisscrossing.
