Okay I've done a bit of research but I'm still totally confused. Can someone help me?
I have a 2003 Boxster S with a fibre optic Becker CDR23, two standard dash speakers, and no amp. I'd like to upgrade my stereo but I'm not sure what I'd need to do it. I understand that the issue is either the fibre optic cables, but I don't even know what those wires do in the system. Does mine even make use of the fibre optic connection? As it has no amp.
Is there a simple adapter kit I could buy that would simply allow me to fit an aftermarket radio?
Help please

would love some clarification as I'm confused to hell and back. Thank you!
