I've got three components: an older (120/160 watt) Workingman 15 combo, a Workingman 1x15 cab, and the Workingman 4001 (that right?) 400 watt head. I attach the extra speaker to the combo, she sounds pretty good, but the works overheat and the power cuts out about halfway thru my set. So I get the 400 watt head. But then I notice that the 1x15 says "rated for 200 watts". I'd guess that the speaker inside the combo is rated the same. Is there a way (series or parallel) to hook the two 15" speakers to the head so that each sees only the 200 watts it's rated for, or is there no way around it, the speakers will fry, the head will burst into flames, and my Warwick will sprout wings and fly away?
