How to remove hum from car cassette adapter.
I have a car cassette adapter to allow me to connect a digital music player to my car's stereo system.
Unfortunately, my listening experience is killed by every time I step on the gas pedal I hear a whine that increases in frequency the harder I press on the gas pedal (presumably the fuel pump), in addition to there is a constant hum (presumably the spark plugs).
These cassette adapters unfortunately use unbalanced unshielded lines. That seems perplexing to do that in such a noisy environment as a car, but perhaps cost saving was the motivation, as this only cost $3.99 at Walmart.
Is there any way to cancel out hum on the line, perhaps buying speaker wire and winding two speaker wires in opposite directions around the line so that any hum will be canceled out before it reaches the line conductors?
