I have recently bought a 2006 Mondeo ghia 2.0 TDCi which has the Sony 6cd head-unit. I have a couple of faults regarding the sound system which i'm hoping someone can help me with.
Firstly, the passenger speaker has developed a slight crackle at high frequencies but also it cuts in and out like there is a bad connection somewhere. I have had a look behind the door card but with the speakers being part of a larger unit i didn't want to dig much further until i have had the head-unit out to check the connections there first (waiting on delivery of the keys to remove it).
Is there a known problem with wires coming lose or speakers failing in this way?
Secondly, I have very poor radio reception on both am and fm, but it sounds more like some sort of interference as it is constant (still present when my previous car would have a good signal). The sound of the interference changes but never disappears.
I am thinking it my be some sort of electrical interference, as i found out this morning when trying to listen to an AM station, that when i press the button to cycle through the trip computer i get a burst of interference each time i press it.
I have read on other posts the the first check should be to check the base of the aerial behind the interior light which i will do when i get home, but with the symptoms i have regarding the trip button i though i would create a separate topic.
BTW, cd playback seams unaffected by this interference.
Thanks in advance
UPDATE: After doing some investigating and a check of the aerial (which wasnt too bad) i descovered that the interference is only there when the ignition is turned on. If i have the ignition on and then turn it off after about 20 seconds the interference goes away. I also tried with the radio on different frequencies and the interference come out as whistling/squealing sound.
I have a video but its not very clear. Will upload if requested.
