Hi
We have two speakers in the living area of the motorhome which are connected
to the cab radio, and now and again they start to crackle when the radio is turned
off, can anybody tell me why this happens

many thanks

Hi Bald eagle.

I can give you some ideas to try,first pull the fuse for the radio see if the speakers go quiet.
If they go quiet it proves the amplifier is still powered even when the radio is off.

Next , trace the speaker cables looking for loose or bad connections.

It is possible you have a slave amp set up and this is powered permenantly.

I have put a couple of PC speakers in mine with the amplifier powered and no input they get
interference from mobile phone's.

Can't say this is your answer...but food for thought.

Good luck.

Speak soon.

Hi martin
I have not tried anything yet, but their is something else i forgot to say.
One speaker is above the tv and the other is above the digital panel,
could this be where the trouble is

Hi Bald Eagle

Tv....Could be but i doubt it...turn it off to prove it.

Digital panel...do you mean the control panel for the water pump and lights as fitted by the manufacturer?

If so it needs looking at, it should cause no interference.

Wish you luck....
