RQ0278E, Rear Speakers aren´t sounding!

[bombass]

Hi!, Suddenly the rear speakers of my stereo died, nothing seems to happen, the front speakers are working fine.
Rear cables and speakers are ok, already tested them so theres is no problem of wiring and speakers.

Any idea?, I think the hardware died...

Thanks!

Hi,
You can check again whether the speaker cable get 6V power and tell me the result.

Hi Jammy, thanks for your reply, but I don´t get it? there are only 4 cables 2X Rear Left and 2X Rear Right?, where is the 6v cable? It´s inside the unit? Thanks!

Hi,
i mean you need to check whether the 4 cables 2X Rear Left and 2X Rear Right get 6V power from the unit.

Noup, only the front speakers are working. Only silence from the rear speakers.

Hi,
Do you mean the rear speakers wires don't get 6V power ?

Hi Jammy, now the 4 speakers are not responding. Think the amp of the radio is broken.
The wiring harness is connected ok.
All the other radio functions are working fine.

Any idea?

Hi,
sorry for my bad english.Did you try to check the voltage of the speakers cable using multimeter?
If the voltage is much lower than 6V,that means the internal speaker circuit are broken.
Could you tell me the test result?
In addition,Please first tell me your order number in amazon or buyer id in ebay,Pumpkin or AliExpress so that we can confirm more information about your unit and provide you positive solutions.

Hi, sorry for the delay, don´t worry about your English, mine isn´t good too.
I bought the radio on ebay order #182347852631 Ebay ID: bombass2010

The speaker wires shows no voltage through multimeter.

Thanks.
