Hello. I would like to upgrade my 850s acoustically and now had the opportunity to reserve the complete SS from a V70 I with SC900 radio for a short time.Included: Radio power amplifier adapter cable extra CD changer 6x LS amature board LS doors front LS doors rear LS D-pillar I hope you can help me with these open points before the big football spectacle attracts all attention: – Is this the premium package or is it even better (I don’t have more information at the moment)? – Radio should fit, or (so far only a simple original DIN cassette radio is installed + storage compartment)? – where do I put the power amplifier? – which LS are compatible (at least those in the amature board are different in the V70, can you install them with an adapter nevertheless)? Cables for the LS are all available with my vehicle. Already in the foreground nice thanks. kc
