Question, as you look in the boot, the left hand side compartment, what's supposed to be there? All I have is a circular electrical connector flapping in the wind? CD changer or something?
Yup cd changer, I've got one if your looking to replace it lol
You press Mode IIRC.
Concert (and its associated CD Changer) is a bucket of ****e anyway, i wouldnt bother replacing it, get yourself a decent head unit instead.
If the changers not present the option vanishes from the mode list.
The headunits are riddled with faults like you say, they're also ancient and have no modern features.
The concert head unit does have pre-outs, and if you're determined to keep it, then i'd still go down the route of a sub amp and discreet amplifier for the door speakers. The output from the concert is woeful, and the stock speakers cant handle any bass, however once you give them a nice signal and feed the bass elsewhere, they sound pretty decent.
Paresh did that and was pleased with the results, although he had the later symphony unit, the same idea will work with your concert.
Theres no easy approach to changing the door speakers. The stock speakers are mounted oddly, the commonly available plastic adaptors are absolute garbage and a waste of time. If you want to change the speakers it essentially means mega effort making up your own mounts.
I fitted some nice speakers to my first avant, and they sounded worse than the stockers. On close inspection, i could see that the plastic adaptor was stopping the bigger speaker cone moving freely, hence it sounding rubbish. I ended up putting the stock ones back in and selling the speakers on.
