Anybody have any suggestions for this? Installed my jensen lcd today, and a sony 12 v. vcp and fm modulator. Hooked the vcp to the power outlet under the center console (cigarette lighter socket). When I have the vcp on and the engine running, I can hear a whine that increases or decreases with the rpm of the engine. When I am just using the television, (which I have hooked to a power source in the fuse panel using the "add a circuit" mini plug), I have no audible engine whine that I can hear. Is the audible engine whine when using the vcp with the cig lighter as the power source due to using the cig lighter as the power source instead of some other power source, or is it related to the vcp itself? Thanks for your help.
