If your speaker/amp setup worked with a standard stereo before, it will work with your carpc. Check your carpc sound settings. Make sure you have your headphone jack configured the way you expect/want it to. Most will run it in Stereo or 2.0 mode and split it off. I would guess from your current setup, you want Quadrophonic or 4.0 mode, and make sure your subwoofer input is coming off the front RCAs, NOT the rear.
I had an identical setup to you (4ch + mono amp), and ran the Carpc configured in 4.0 mode. It worked just fine!
ill mess wiith it but what do you mean front rca's

then that means that there is a ground loop problem-- where the power has a easier time using the audio cable for ground instead of the specific power connections that you installed. time to learn how to fix a ground loop ;)
By front RCA I mean the cable coming off the "front speaker" output in 4.0 mode on the back of your carpc mobo. Generally, when you have your computer setup as Quad/4.0 mode, you will have NO bass output to the rear speakers (rears were never designed for bass, and Windows won't output it that way, either.)

Soundman is right, if you have a lot of interference, you have a grounding issue. Make sure your power supply is properly grounded. Are you using a carpc designed power supply like an M2 or M4-ATX psu, or some type of inverter that goes into a cigarette lighter?
Also, just FYI - most mobo speaker output is limited to 5W per channel (compare this to normal stereos that are 30-50w per channel), as almost all computer speakers are powered, whereas car speakers are not. You may have to increase the gain on the amps significantly to get the same volume from a carpc as an ordinary stereo.
