If you want to use original amp, you will have to use pre-outs on new stereo and add phone plugs to existing amp inputs.
I did this on my previous is200 and sounded great.
Will post wire colours if needed.
Hello and welcome to the club Colin, nice example of the marque you have there.
There's a meet on the 24th August you might be interested in, see my sig.
Im positive the ls400 owners will be along shortly.
Ian.
Im 46 so insurance is quite cheap for me BUT still don't understand why an is300 worked out cheaper than a 200, even insurance people hadn't a clue why?
Stangely Ian, everyone says auto are more thirsty but i have found mine to be ok, Not great locally i admit but on a journey to tunbridge wells and back, 2 up and using cruise i managed an average of just over 40 mpg.
100x5 is the pcd, has to do with stud/wheel bolt spacings, you can get away with 2mm or so with "wobble bolts" but not 14.3mm. The ET is the offset number.
Hope this helps, Ian
