Does anyone know how to wire in 2 head unit into 1 set of speakers. Just got a dvd player and already have a cd unit wired the dvd in but speakers. What i want to do is on long jouneys listen to cds and the kids watch dvd with headphones but if stopped watch films with speakers and cd head unit off. Any ideas ?.

What exactly are you trying to do? Do you want the kids to have headphones on whilst watching DVDs? and you want to listen to cd, is this correct,has the DVD player got an headphone socket? if so plug the headphone into that. You could use somekind of speaker switch ,to switch between DVD and CD source, not sure if this would work though but it could be worth a try.

You've got two options:

1. Use a few relays to switch the speaker outputs over
2. If one of the head units has an aux in, or an aux in adaptor option, use that :D

I'd go for option 2 if at all possible.

cheers is there such a thing as a speaker switch, ive heard of scart ones.

You can get them from maplins , but they are for home hifi would of thought they would be OK though, don't know if they allow multi-input though?

nice one will find out thanks
