Thread: Mazda MP3 Project part II

You know, it occurred to me tonight, that since I have had a halfway decent sound blaster Audigy 2 Value card for sound out of my car PC for a bout a year now, maybe I should try running 4.1 or 5.1 Surround sound? All it would take are a couple of cable changes to the AMP. The pictures below is how I first set it up (an how it is now), due to the fact that my old Carputer was a laptop on a docking station, with one audio out. Notice that I merge the Front Left, and Rear Left together, and then Front Right and Rear Right together, and then feed them both, via Y-Adapter to a regular RCA Right-Left, down to one line to go to the line out on my soundcard. The last picture is the reference I'm going to use to setup 5.1 Surround Sound for my soundcard:

Thanks. That little dinovo looks sweet too.

Here is a picture:

Ok, So I just got rid of the old, krappy unshielded wire, and put in some new, less-krappier shielded wire. I may have just solved my grounding issue....

that radio shack stuff is the unshielded im assuming?

No, if the package says shielded, then it is (it says shielded). It just doesn't look pretty like the orange Hooker Audio cables. I went for a drive, and I believe I have finally gotten rid of my alternator whine, by replacing the cables with Shielded cables!

So it turns out that I can only run 4.1 sound right now, due to the fact that it doesn't make sense to power my stock sub with my AMP (as it would be too much). I will have to wait till I get a decent SUB to do that. So I went and got another RCA cable, and I will be setting it up shortly. Below is how I will have to do it:

Updated the first posts with new pictures of stuff I've done in the last year.

Are you still having audio problems with the static and noise from computer actions? I've had the same problem. I tired everything....changing grounds....plugging in two Ground loops isolators at a time....nothing worked. Finally I figured out, it was the motherboard. I swaped out the DFI board for a intel d201gly2 little valley board and it's been perfect. No noise or static, just crystal clear sound. Hope that helps

Interesting. I did a work-around by using digital SPDIF-IN for my Sirius audio.
