  • Tda7850...

    Started putting together my first carpc and been reading up on what people have done regards to audio and just wanted to see if I understood it all, and what I have planned will work ok!

    Will be running the onboard audio from a D945GCLF2 motherboard... Which if I understand the specs can run 5.1 through the back I/O audio jacks?

    Will wire these into a TDA7850 4x50w amplifier, and then into the car speakers...

    Im not after mind blowing or eardrum bleeding levels... just a simple/minimal fuss way to get headunit type audio.

    May even be over complicating it trying to get/use the 5.1 out of the onboard from the mobo?

    That amp should work fine for you. If the onboard doesn't do it for you, get a usb external sound card. Good luck and always start a worklog and post lots of pics SNO

      Appreciate the reply,

      Yep, my next idea was the external usb soundcard if the onboard doesn't work so well!

      Worklog will be up as soon as I start putting the parts together for testing etc... In the middle of working out the best gps device to use... seems the most popular device is a usb globalsat bu-3** just trying to figure out the best place to get one.

        I would suggest you just run 2.0 out. You likely don't have any music that was recorded in 5.1 and you apparently aren't going to use a separate sub woofer so you want all of the left & right channel audio available to the amp's respective L & R channels. Just y-cable the front left to rear left on the amp and the same for other side.

        Simplest way:

        from the PC with this:

        Then to the amps with these:

        Then a regular RCA-RCA for the rear channel inputs.

          I would also get TDA7850 with denoiser. Much better than the standard TDA7850. You can find them on ebay for around $30

            I did wonder if trying to use the 5.1 would be over complicating it...

            Appreciate the info and links!!

              I ordered one before coming across the ones with the filter, coil etc, was only 13.80inc delivery so can always order one with if it proves problematic.

              Thanks for the info!

                Been sorting out the wiring...

                3.5mm Stereo Jack Headphone Earphone Y Splitter Adaptor x 1 (Link)

                3.5mm Male Jack to Dual RCA Two Phono Plug Audio Cable x 2 (Link)

                Think this is the easiest way to do it... If I can get the splitter in the Line_out with the other plug in the Line_in!

                If not... I'll have to use one of these!
