    With Zebelkhan's solution, he is able to play both at the same time. Radio/CD coming from car speakers while GPS coming from a small speaker.

    And when he wants to listen to CARPUTER with his car speakers, just flip the switch!!!


    Now my question is, how do I build a switch that switch between 2 different sets of 6 channel sounds? My headunit has 5.1 output and so does my carputer. How do I build a switch to switch between the two sources going to my amps?

    no, he wants both coming out of his car speakers ideally


    as for your question, use 2 3PDT relays

    I don't know much about electronics but I understand you should not connect two output sources with different impedence levels together as the out put electronics may get damaged. My solution separates the two circuits.

    Believe me the GPS sound coming out of the little speaker is sufficient! It is very clear and its volume can be set to any level you want independently of the HU. Also, because I have the speaker mounted under the dash on the driver side, its sound is mostly directed at the driver so it does not interfere with the listening pleasure of the other passengers!

    Now that I am able to turn the lilliput audio on when in VGA mode, today I plan to do away with the little extra amplifier and speaker and connect to the lilliput audio input instead for a more OEM look.

    Microtime......since you have a 98 there are adaptors available. I will check tomorrow with peripheral electronics to see what they suggest and if a part I know will work for you is still available.

    then how do mixerboards work? they take signals from 2 sources (guitar, CD player, microphone) mix them, and give a single output

    Microtime....Peripheral Electronics makes a part called a SPK. That is a speaker switcher. It is two channel and designed to route a signal from to sources to a single set of speakers. That should work for your speaker switcher.

    They also make two other parts that allow you to have an aux input to your factory radio. These two parts are supposed to work on 98 Toyota factory radios.

    Those parts should be able to help you at least get started. What would be best if their was a way to output 12v from your computer before the GPS talks. If you could do that then it is easy to make a relay switcher that would allow the GPS to override anything that is playing through the speakers.

    Like I said I don't know much about electronics so I could be wrong, or, mixerboards have something specific that deals with it. I am sure they are more than just a knob. All I know is that I have mixed two outputs (an old stereo and a tape player/recorder) together to a single set of speakers and after a while my stereo sound got really sick!

    I think I found it....

    I saw this on another posting. I believe this will do it without me having to make a circuit on my own.

    I can't believe this is that hard to do. I'm amazed I'm the only person who wants a head unit and a PC to make noise automatically without a switch or the like....

    Next time I wouldn;t have gotten a Mocha but did a smal form factor Mobo somewhere else. This way I could have had a realsound card and not have to rip apart a USB Oronico WIFI card. My kingdom for a a few PCI slots...

    Not to disappoint you, but I posted this last night and deleted it, because I didn't want you to FUBAR your speaker system. My Kicker amp also has low level & high level inputs, however it specifically says NOT to use them at the same time. Not sure what it will do, but smoke and sirens spring to mind.

    Here is the illustration from the manual:

    ok guys think about this

    when you take a stereo (2 channel) amp and bridge the outputs, you are connecting 2 separate amps together.

    what's the difference here?
