theoretical about separat pwr cable/RCA. i dont think ur systems engine noise is cause by no separating cable/rca, i tested this on an integra and nothing change.
you notice on certain cars, especially hondas...they have this high pitch engine noise as you rev the engine. i think i figure out why. if anyone whos a dork like me to study cars and stuff to figure out what the hells goin on, if you ever look in the distributor housing, theres the internal ignition coil and theres another little cylinder called coil condensor(if theres any). i think this lil sucker is for filtering out all the interference cause by the electromagnet from the coil to the rotor shaft. remember that the rotor shaft is conduct through the engine/ground/frame/chasis. i think these older hondas that use distributor doesnt have a coil condensor to filter out all the interference.
just a theory i want to share.

Nice try, but no banana. The noise you are referring to can be caused by numerous problems in vehicles, be it a bad power supply or ground in a deck or amp, no ground strap from a hood, poor battery to chassis ground, poor ground from equipment to chassis and the list goes on. One thing that most of these whining noises have in common is a grounding problem of some type. At one point in time I could guarantee noise in certain model year Toyota's when Pioneer cd players or tape decks were used, yet no noise at all when Alpine heads were used. Do you think it was the vehicle or the design of the power supply in the Pioneer head? A bad voltage regulator or leaky diode can also cause noise headache's, but nonetheless, you may have also stumbled onto yet another cause and posted up for all to see. ------------- Top Secret, I can tell you but then my wife will kill me.

no, am not having this problem at all. i fixed my car and just happen to stumble on this component that may interfere w/ other cars, not my car...especially hondas/acura.
the component that i mentioned above, you know what am talkin about? if you take out ur distributor, thats if you have one and check

I'll have to agree with forbidden, with the grounds, but you "profuse007" also stumbled upon a device that does cut out noise, but just that isn't going to stop all engine noise. Like you said. I once had engine noise, then i ran about about 10 grounding wires from different componets on my engine with 8 guage wire, and ran all te wires to 1 grounding location, and voila, my noise was gone, and i noticed a little power gain, wtf, eh, haha now i see people selling kits on e-bay for $20 for doing exactly what i did, for PERFORMANCE gains, lol, , , i stumbled upon a new concept 2 years ago, to bad i didn't market it then, errrrr
