i want to use stk439 amplifer which has 42 watt output with 7 watts
speaker. how can i do it without blowing up the speaker.

Just don't turn it up too loud - ever - and it should be OK.

can i limit the volume somehow. maybe placing a resistor in series
with the volume control variable resistor?

Heavens, yes! There's nothing to it! Find out the resistance of the pot,
and make a voltage divider.

The arithmetic, as usual, is left as an exercise for the student. ;-)
