hey, i was wondering anb out something, ive been playen guitar for a wile and jus got a dual rectifier and joined a band, i have been playing the head threw one of there extra carvin cabs but want to switch the carvin for a marhall 1960 412. to hook up to cabs, my mesa has two 4 ohms. two 8 ohms, and one 16 ohms out put. on the marhall, shoud i hook threw the 16ohms? i dont want to end up trashen the cab. and one more question, would a head that plugs into a single 412 cab with a 4 ohms out put be way quieter then a head pluged in to a single 412 cab w/ a 16 ohms output.
thanks
matt

I forgot which way it was safe to mismatch impedence, but I'll give you a hint - everything I know on the subject came from a Mesa owner's manual. Have you read yours yet?

You are better off matching the impedances, i.e. 16 ohm out on the head to the 16 ohm mono plug on the cab. Mismatching is USUALLY okay if the speaker load is greater than the rating on the head, i.e. 4 ohm output on the head to the 16 ohm plug on the cab. A) notice I said usually, if you push it hard and loud there is the possibility of it overheating the output transformer and B) it really won't make that much difference volume wise, you probably won't notice it so why take the chance.

just to throw this out there to think about.. my 2 mesa 1x12 widebodies have more low end and power than the marshall 4x12.. you may consider just buying a mesa cab before you trade your carvin on a marshall cab. that way you will be sure to match impedience.. my two cents
