So I just installed my car pc and Im getting noise through the speakers. Here are my system specs:

Carnetix P1900
Sony Laptop
External Creative Audigy 2 NX

I have my stock sound system for my car. I installed one of these to plug into my OEM amplifier:

I have plugged computer speakers into my external soundcard after it was installed and there is no noise. I have also moved my RCA cable away from any power cables, but dosnt seem to help. There is very minimal static when the PC is not on, but it gets alot worse when I turn the computer on. It also kinda seems to be linked with the loading of the laptop, as the sound fluxuates when I do processor intensive actions. I am powering my laptop, LCD screen and external card with my P1900. Everything is tied back to a distribution block which is tied to my chassis. Any sugessions?

Check all your cable connections to make sure their in good, and also check all your grounds for a secure connection. Clean the area where your distribution block ground, make sure there is nothing keeping from ground like dirt, grime, or paint.
