Need help on Whinning (Aeroplane) sound from ICE

[Vincent Hor]

Car running on Blaupunkt Bremen MP74 HU, Blaupunkt 4 channel amp GTA450 & Blaupunkt Active SubWoofer ODsb8000A. Last Sunday removed the active subwoofer to do so cleaning in the booth area. Now after reinstalling, encounter this problem. It's so irritating that I don't even want to turn on the system. What could be wrong? How to rectify? Some said earthing, aux jack or amp shorted problem. Those in the know, please advise.

Vince,

Check all your connectors. Most of the time, this RF interference is due to a weak grounding point somewhere in the system.

Thanks. Thought that you will share your input. Will do all the wiring check over the weekend. BTW any good accessories shop to recommend?

Just to update. The problem solved by a friend recommended shop Sri Kuching Car Audio along Jalan Kuching. Quite careful and knowledgeable guys. Ran some test and found that the problem was from the HU itself. Resolved by adding gounding. Thanks Kev
