Connect 2 speaker cables from 1 HEAD to 1 CAB?

I was going to do a RTFM on you, but after reading it I can understand why it might be poorly worded. Other vendors do a better job of documentation, illustrating the speaker wiring combinations supported. But as a rule of thumb, there should never be more than one cable between the head and a cabinet, regardless of make and model. The PF series supports connecting two separate cabinets, or you could daisy chain them, depending on total load.

Hopefully Jesus has a manual, if not he can download it here:

I also looked at what they said about using the output jacks. They say you can use either one, or both.
They really don't discuss under what conditions someone would use both. "...use both to connect to two speaker cabinets." Would be more clear, IMO. So I can see how someone might not be clear about why you use both. They also give examples of loading, but again that assumes one knows what the impedance of their cabs are or understands these terms. Sometimes a little extra info can make, or break an explanation.

PLEASE ALSO NOTE FOR THE RECORD... They do advise, in the manual, against using instrument cables to connect speakers. Which is very good advice. DO NOT TRY THIS AT HOME. My example was an extreme and unlikely situation and also warned about doing this.

I give them a B+ on the manual. I've seen a lot worse.

Thanks. I should have further illustrated by saying:
There are two amp outputs so you can feed two cabs.
There are two speaker inputs so you could feed two cabs if your amp only had one output.
In that case, you wire amp to cab 1 and then link from cab 1's second Jack to cab 2.
Regardless it is all wired in parallel no natter how you string the cables.
If you want more volume you can add a second cab (being sure both cabs are 8 ohms each) this will allow your amp to supply it's full power output (500 w @ 4 Ohms / 250 to each cab) and will also give you more volume due to the added speakers.

well, you dont have to daisy chain the cabs. you can go out from both amp outputs - 1 to each cab. I prefer this way...no particular reason, just always connect both cabs back to the amp. One less point of failure.

Assuming that both speaker cables are wired correctly, it would be no different than using a 4-conductor Speakon cable. Nothing bad will happen. All you'll do is lower the resistance of the speaker cable, which means you'll be able to drive more current on transients, but it's not likely to be any noticeable difference if they are good high quality speaker cables, since high quality speaker cables should be designed to handle the power.

You'll gain basically nothing, but you won't hurt anything.
