BAAD PROBLEM

[Turkboy]

Im here in turkey right now and my cousins friend is having alot of trouble with his amp. He took it to an installer and they did something idk completely because im still trying to remember turkish. Anyways after he said about 2 days later it started making this super weird noise so i wanted to hear it and see it and maybe I could do something but i didnt get a good look at the amp. I came to the forum bc everyone is always helpful and a little hands on experience will be good for me. This is what happens he connects the white RCA into the ch.1 jack and this high pitched humming comes out and when he disconnects it it stops (der) and the sub has no functionality either. Im going to get a better look at it tomorrow and see because its late here and i'd rather see it during the day anyways.

thanks in advance!

The subwoofer is making a 'high pitched' humming sound... As in motor noise? Do you mean the speakers are making a high pitched noise and the sub isn't working at all? Either way, check the grounds on the the amp(s). If that isn't the problem, try adding a ground to the heat sink on the back of the deck. A temporary one with some jumper cables will save you some time analyzing what the problem is.
