No sound from Pumpkin AE0273B

[Robc]

Juts installed this unit i bought from AliExpress Order Number: 93026429447318.
I get alternator whine and popping when i turn the head lights on through all speakers. None of the speakers put out any sound (radio, media etc.)
the only speaker that works is the subwoofer. rear speakers which i have running of the deck power do not work just static, front speakers that run off the low level inputs running to an amplifier running to front speakers no sound just alternator whine. Just replaced my sont unit with this unit and it was 100% working fine. please advise a solution. I was vary hesitate in buying one of these units, and i am disappointed.

Its ok I got the sound to work. Though I am getting the low hissing noise which is not affected by volume that seems to be quite common from these units. It will go away when volume is at 0. Has there been a fix fr it yet?

Hi,you can consider adding a magnet ring filter to the power cable (the yellow wire and the red wire) .
