Not Engine Noise but static
I've had my pc in my car about 6 months now. I have a HP slim line pc being powered with an inverter I just added a kicker 3504 4ch amp and a kicker 7501 sub amp Im using the onboard sound card right now using 3.5 mm to rca adapters to the amps using front rear and sub outputs. I am not encountering any engine noise or whine but I'm getting a low level static through all speakers. when i remove rcas from amps there is no noise its only while playing music from computer. Any ideas??
