will this configuration damage my speakers ????
I will get a 4 ohm amp as soon as possible, but in the meantime, i was wondering if i can get by with this temporarily
Unless there is a specific warning on the amp or in the manual against using the amp with 4 ohm speakers, you should be fine.
Most amps will work with either 4 or 8 ohm loads, and sometimes they will even list the power rating for both types of loads.
As long as you aren't cranking the amp to its limits, you should be fine. It's only when the amp starts to break down from being overloaded that it could send too much current to the speakers and fry them.
