two radios and two sets of speakers - wiring?

[bioboat]

Hi all

I live on a boat, and having a 12v system use a car stereo and
speakers. Everything works fine, so maybe it's time to try something
different...

For various reasons I want to install a second car stereo into the
boat, alongside the first. Obviously it would be too easy to wire them
up to seperate speakers, so i'd like to wire them up so that you can
choose whether speaker set A is wired to stereo A and speakers B to
stereo B, or vice versa, or all speakers taking the output from one
stereo.

Any ideas how i might do this?

many thanks for any advice

ISTR Maplins do something that might fit the bill.
