The rear speakers in my wifes' Mini (X-plate 2000) started making an awful sound a few weeks ago when she started the car - the radio was not even on! Now, there is a 'pop' when the car is switched on from the right speaker followed by hissing, and nothing from the other. The battery has started to flatten - seemingly for no reason also.
On Friday when I opened the boot to investigate the flat battery, I noticed the hissing sound coming from the right speaker, even though the keys weren't in the ignition. So far I have checked:
- voltage on the speaker feeds when the car is not turned on - 0.012v
- voltage when the radio is on - LH speaker no change, RH speaker 2.89V
- impedence of each speaker - both 4 ohms
- continuity of the speaker cables unplugged - open circuit
I am beginning to suspect the CD player - it's the original unit.
Any other ideas?
Best regards,
