Hi All,   I know about ohms and delivering full power from amp heads etc. But have would like some advice or thoughts on the below.   I have a 500 watt head and a 350 watt head plus a single 12" cab.   My thinking is to add an extra cab to the 350 head or use the 500 watt head with the single cab.    I play in a 4 piece soul/funk band.   Welcome thoughts.   Stu
