Keith's point was that you can't just add additional speakers in 
parallel without consequences. Adding speakers in parallel will lower 
the resistance of the load that the radio is trying to drive, asking 
it to put out more and more current. At some point, you'll fry the 
radio's output transistor.

One way to get around that would be to wire the 2 rear speakers in 
series, which increases their net resistance. That will cut down the 
output from those speakers, but make damage very unlikely.
