Ohms Law My Guitar amp has 16 ohm or 8 ohm outputs?
Ohms Law My Guitar amp has 16 ohm or 8 ohm outputs.?
The internal Speakers are each 8 Ohm, (2 of them) wired series to make a total of 16 Ohm, (if i re-wire them to parallel i get 4 ohm right?)
Now i want to buy an extension cab that is a 4x12
Its total impedance is 8 Ohm... How should i go about connecting it? If you need more info let me know i think thats everything though... normally i can do this kinda math but its confusing the hell out of me. Thanks in advance,
Josh

Ok you have 2x8 Ohms in series to make what your amp "sees" as 1x16 Ohms.
If you cab is 8 Ohm it probably has 4x8 Ohm speakers wired in series/parallel IE. they are wired in pairs in series, the same way as your internal speakers, to give 2 separate pairs at 16 Ohm and the two pairs are then wired together in parallel as if they were 2 individual speakers
Your options are basically to change the speakers in the cab for 4x16 Ohm series/parallel or unplug the internal ones when you use the 4X12 (common practise!).
Some info on your amp may give a better answer
