JVC CD tuner fitment - Peugeot 106 - howy868
Has anyone got experience of fitting a JVC 45Wx4 CD tuner (or other brand) in place of the OE unit on a Peugeot 106 1.1 XN (late 96 facelift) version or similar trim level model.
The iso cable connectors from the JVC unit look identical to the OE unit, but there are dire warnings in the JVC manual about how certain speaker wiring configurations, eg commonised return speaker wires, will cause serious damage. There is another forbidden speaker wire configuration but I cannot understand the tiny diagrams (can bearly make it out with my eyesight!!).
The car only has 2 speakers for now but I presume that the 2 rear amplifier stages can be left with no speaker connected?
I was also wondering if I am likely to find some redundant rear speaker cables in the loom. Would make life easier if I decide to install a pair of 6x9 speakers on the back shelf later.
Any help is most appreciated.

Thanks
