It is a most fibre optic system I am told .

Anyway, I was considering replacing the head unit with upgraded sound and technology, to an 8 " alpine unit with new alpine 5ch PDR Amp.

Any thoughts on the best system out there.

Ideally I want the largest screen out there that will fit in the standard Porsche opening (8") I think.

I will keep all the standard kit should I ever sell

( unlikely )

Recommendations / thoughts appreciated.

My car is a 2005 Turbo S .
