Ohm and impedance calculations question

Are you talking about hooking that cabinet at 8 ohms stereo to the same amp......hooking both sides of the cabinet to the marshall? In that case you'll have a total of 4 ohms.
It's the equivalent of hooking two 8 ohm cabs to your Marshall which would result in a total load of 4 ohms.
All that switch does is separate the 4 speakers into two pairs. They are probably 4 ohm individual speakers so when they are all hooked up it's 4 speakers in series which totals to 16 ohms. When they seperate them.......you have two sets of 2 speakers. Each pair is wired in series so they are each a total of 8 ohms. Then if you take those two jacks and plug them into your Marshall......you'll be running those two pairs in parrallel............two 8 ohm loads parrallel is 4 ohms. So.......if you're talking about hooking the cabinet only to your Marshall.......your choices are.....16 ohms........half the cab at 8 ohms......or both sides in stereo comes to 4 ohms.
I'd probably choose to go with the 4 ohm load.

And since that's the least they'll let you use; you'll probably be putting out about 100 watts . But, once again, you can't really figure out what you're amp will put out into a speaker just based on the speakers nominal impedence.
And all the horror stories of amps catching fire and stuff are somewhat exaggerated and almost always involve some additional stupidity on the part of the user. Just don't go below 4 ohms and you should be fine.

thats good to hear...see kids? stay in school! pay attention so you dont fuck up your amp later on in front of drunken college groupies!
