The 4 ohm rating on the amp is the minimum rating ohms
( dont go below this ,2x 4 ohm cabs would run at 2 0hms and cause damage)
using 2 8 ohm cabs means you are running the amp at 4 ohms
and getting the full 300w power of the amp
if you run just 1 x 8 ohm cab you will get approx 210w of the 300w
should be fine i do a similar thing with rehearsals ,it saves humping around loads of gear.
