ONLY ONE SPEAKER WORKING
 

Dear All,

i have E53 4.4 2004 model with audio system (TV + CD changer)
the problem i am currently facing that the sound is coming only from rear left door !!!
i tried to adjust the fade & balance with no hope
it is happening with all types of playing modes (CD, Tape & Radio)
can you please advise the possible causes and the way forward

thanks in advance

any ideas?

you did not mention if your car has a Bluetooth, navigation... if you have BT, can you hear anything? the BT operates the two front speakers in the front doors...

Have you checked the wiring at the Amp? you did not say if you have DSP... do you get any crackling sound from any other speakers?

since the problem seems to be with more than one speaker, the issue probably lies within the amplifier/DSP plug... check to see if the plug is secured in its place...

I don't have DSP or Bluetooth or navigation
I didn't try the phone, the eject box need replacement
Is it possible to advise the location of the amplifier and if possible the part number
Thanks

radio tuner?

please advise what to check with radio tuner?

I couldn't really tell you what to check to be honest. It could just be dropping channels. Awhile back, the entire right side of my car was not outputting any audio. I checked the amp first and the connections were corroded. I cleaned it and nothing happened. I was advised to replace the radio tuner. Ordered one online and all my speakers were functional.

thanks :)

I checked it and the amplifier is defective :(
I'll replace it, but can I put DSP one (plug and play) or have to install non DSP (as the original setup)
Thanks

We have changed the amplifier and still same problem :(
We are suspecting the radio module on back trunk near the battery
