This is a first post by a new user so let's hope it's OK.
I have a 3 door 2001 A3 with a standard (non Bose) sound system with a sub in the nearside boot locker.
I have a problem with losing all of the rear sound. It started as an intermittent fault but has progress to being the norm. There is sometimes a faint clicking from the rear nearside (sub area).
I have had a search around and found a few possible solutions:
Wiring fault - like the wires have parted somewhere and are causing an intermittent loss of sound
Amp fault - connections or possibly dry solder joints
Speaker fault - sounds the most likely - one of the rear speakers or the sub is 'shorting' and this causes some kind of overload protection to cut in and turn off the amp
Has anyone had this fault and cured it? Can you let me know what to check, where to look, advice about removal of panels may be needed too.
If the amp is shot, is it better/cheaper to replace with an aftermarket one.
