Ummm you don't to do that.  If the advice given was to source 10ohm - 3 watt resistors then get the correct ones.  There is obviously a good reason for it.  Failing to replace resistors with identical specifications may result in a much worse outcome.

Radio Shack sucks by the way.  Go to an electronics store/retailer.  There are more common than you might think.  Open your Yellow pages and inquire.

You could substitute 10 ohm 5 watt, or 10 watt resistors.  Just as long as it dissipates the heat.  You could also use three 30 ohm 1 watt resistors bundled in parallel for a 10 ohm 3 watt result.
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Alright, I was able to get 10ohm 10watt resistors, so hopfully these won't give me any problems. They do look very different from the reular kind of resistors on the amp.
