Hello. Yesterday I installed a new android system radio. The problem is that you can hear continuous hum through the speakers of these small tweeters. The noise remains the same no matter if auto runing or not. My car
Tuareg mk1 04.r
The audio system 11 speaker and the amplifier in the trunk are original. I checked ground is good anyone knows what could be?

Reading other posts, I understand that it is about signals from the radio to the amplifier? Can anyone help me and explain where the problem is and how to solve it?

It is virtually impossible to diagnose a fault in the wiring of a radio without knowing how it is connected. You don't even say what make or model the radio is or how you went about installing it. What have you tried so far?

Factory radio is a delta and digital amp. The new radio is a multimedia system from Ali expres 195.12US $ 52% OFF|IPS DSP 8 Core 4GB 64GB 2 Din Android 10 Car DVD Player For VW/Volkswagen/Touareg/Transporter T5 2004 2011 Multimedia GPS Radio|Car Multimedia Player| - AliExpress works properly ..

Is the audio clean with the tweeter disconnected?

Yes

Yes

Its is probably the way the tweeter is wired to the speaker. I would install a crossover and connect it properly.
