I've bought a peavey classic 50, which has two 12 inch speakers. The speakers have "8 ohms" printed on them. It's a great amp, and a great price too!

It has 2 speaker outputs, one labelled "8 ohms", the other "16 ohms"....currently it's connected to 16 ohms, although I can't be sure that this is correct, since a) it's 2nd-hand, and b) my friend accidentally unplugged the speaker cable and wasn't sure which one it was plugged into orginally!

Anywho, which of the 2 outputs SHOULD the speaker cable to plugged into?

Many thanks!

Not sure. Are the speakers connected in series or parallel?

If the speakers are connected in a chain, like jack=> + terminal, - Terminal to + of other speaker, = of second speaker back to the jack, it's in series, plug it into the 16 ohm jack.

I'm making a diagram for you.

just looked at the speakers and there's a wire going from the negative of one speaker, to the positive of the other....so it's in series (right?)...so the resistance is 8+8 = 16...so it SHOULD be plugged into 16 ohm speaker output?

Ok, I'm hijacking the thread

I have a 4 ohm cab, but my fireball doesn't have a 4 ohm output... should I use 8 ohm output instead?

Its parralel wired, and 2 8 ohm speakers.. That makes it 4 ohm right?
1/8 + 1/8 =

^NO!

Rewire them instead. What cab is it? Also can you use other options besides 4 ohms?

I can't rewire it.. Have no clue how to do it,, =\
Its home made, so no changing ohm... If i'd take off 1 speaker, would that make it 8 ohm?

You'll have to solder maybe 6 joints at most, its worth re-wiring it.

Your tone will change & you'll probably lose volume.

2 8ohm speakers can only make 4ohm or 16ohm. 2 16ohm speakers would generally be used for 8ohm. It's good advice to remember.

Well if you don't know how to do it, either find someone who does or a tech who will do it, should be VERY cheap.
