. i think after doing some research it seems that the peavey tour 450, which is 450 watts at 4 ohms, will power an 8 ohm speaker, but less efficiently, and would be more like 225 watts at 8 ohms, which seems it would be safe for the speaker, and the amp. hopefully, we have a gig today. i think if it were a 2 ohm speaker, i'ld be in trouble.
