Improving the fidelity of AM reception audio

[asynchronousman]

That's about it, Bob, but this is a trick some of us want to do to our vintage SS receivers, if we are truly lucky enough to have ANY music stations left. Take the instance of my current GM Theftlock AM/FM cassette unit, which has a moderate response (yes, plain ugly FLAT with a little bass but better than some). Assuming I manage to deal with the code, I would love to figure out how to widen it. 1994 Pontiac Grand Prix if I knew the model after driving it only 8 days I'd run for office.
