I've tried the search function but only finding detailed stuff on aftermarket stereos, not the original.
I've just bought an IS200 and although the stereo was fitted he told me it wasn't wired in. It also had a big speaker between the rear armrests which I've now removed.
Anyway, can someone tell me whether both sockets on the back of the stereo should have plugs in? Or should there just be one and then amp feeds the signal to the speakers? There was a bypass lead from the loom to what would have been his aftermarket stereo.
Any info would be greatly appreciated.
Sorry if this has been asked before.
