In 2000 there were 205 million vehicles registered which is probably
around 220 million today. Total population is just under 300 million
living in about 110 million households.

In the 2000 census the average number of persons per household was 2.66,
not four. Suppose there are two occupied bedrooms, on average, and a
kitchen. That's three radios plus two in cars, or looking at it another
way 330 million radios in households and 220 million in vehicles for
a total of 550 million radios. If we add an average of one boom box
or other radio per household that is about 660 million, or three times
the number of registered vehicles. Call it 750 million to be generous,
it is only half the 1.5 billion number that gets thrown about.

I suspect one of the problems with the estimates is not taking a high
scrap rate on boom boxes into account.
