Hey guys, new to the forum. :)

I'm working on a project right now, and I'm in need of some information on relays. From what I have seen, though i may be wrong, a generic relay that can just handle, say, .3-2v, is not suitable for line level audio because of signal degredation. Is this true, and if so, are there any relays out there that can handle line level audio without perceptable loss in quality?

What I'm looking to set up is an add-on to my OnStar interface. I want to set up a 6-channel relay interface box with a two-channel input from the OnStar interface and a 6-channel input from my headunit, then 6-channel output going to the amps. Normally, it would come from the headunit, but when audio is sent over the OnStar interface, it would use the audio source as the control circuit for the relays (or maybe to one relay, which switches the other relays, etc, you understand the point), then would require the driver/user to press a small pushbutton (momentary) switch to go back to the headunit signal.

Anyone feel like helping design the circuit, or does anyone have information on where I can get suitable relays?

There are tons of relays on the market that can accomplish your objective.

Unfortunately, soecing out the proper parts takes a considerable amount of time and of course the circuit itslef.

Try looking up relays at www.mouser.com / www.digikey.com / www.newark.com

Once you think you got something you thnik might work, get the datasheet of the component from http://www.datasheetcatalog.com/

If you have any trouble along the way, I can help!
