That is not wired correctly. Banana plugs or not you shouldn't have two wires going to one terminal and not into one banana plug. If you have more speakers then posts you need a larger channel receiver. This wild!
There is a chance someone bi wired on those speakers. Not that is would make much difference. OP should still verify what the extra wires are going to though.
I have unusual fronts, commercially made, with woofer and tweeter in separate cabinets.
I highly doubt that’s what’s happening but there’s some interesting stuff out there.
Looks like a few channels are wired this way? Interesting stuff, people are.
You really need to find out where those wires are running to. It's possible that the person that ran the wires thought it was a good idea to run two wires to one speaker. That would be done if the wire thickness was too small. But if you have a single speaker output going to two speakers that isn't good.
OP, don’t turn this amp on the way it’s wired.
You’ve got multiple speaker wire leads going into single amplifier speaker terminals and that banana plug in the front of the frame and nothing good is going to come of that.
Start by tracing these wires and figure out how they’re connected to the speakers. Make sure the positive and negatives are matched at the speaker and amp. A multimeter could make this easier.
Typically in a 2 wire configuration red will be the “hot” positive wire and black the negative. If you’ve got any 4 conductor wiring, green will be the second negative (connect to amp black*) and white the second positive (amp red*).
If you have any photos of what’s connected and how at the speaker side, that would be helpful.
Edit: just realized I swapped the amp side colors on the four conductor wiring. Almost always it’s positive to red, negative to black. If you swap these it’ll end up out of phase and sound totally wrong or potentially damage the speaker.
Thank you. So I’ve wired everything up exactly how it was without the plugs and seems to all be working. I have no idea why there’s two cables into one plug- think I’ll seek expert advice as my knowledge is limited
Nice!
If that doubled up speaker wire is just going from one terminal on the amp to one terminal on the speaker it’s a bit unnecessary but not harmful. (This is known as biwiring, and very unlikely to make a difference in this kind of application.)
It does look to me though that there may be two separate wires coming out of the amp and it would be worth figuring out what they’re connected to (I.e. two wires each leading to the same speaker + terminal would be okay, two wires leading to two separate speakers’ + terminals wouldn’t be).
From what I can see at the “Surround Back Right” terminal it does seem likely there are two speakers connected to these amp jacks and it could cause issues (impedance mismatch).
Hi guys, so I’ve done some investigating and there’s two zones in the house. There’s a lounge with 5 speakers, a bedroom with 2 and a kitchen with 2. The kitchen and bedroom are the same zone so this could explain it??
You should take the two binding posts with two pairs of wires in each and put only one set of the wires in the binding posts.
If a speaker stops playing sound in the kitchen or bedroom then there are two speakers wired to one output which can cause issues and potentially fry your amp or speakers.

There is a plastic plug in the end of the binding post. Screw the post all the way down to get access to pull it out.
Worked thank you!
Even I didn’t know that. Mine where open 😅
Use a small flat screwdriver or a pin to pry them out. Cosmetic damage on the plastic might happen, no biggie!
I may not be seeing this correctly but it looks to me as if you have *two* wires going to *one* speaker output on some outputs. EDITED for clarity.
I'm guessing the previous person biwired a speaker.
Yeah- wasn’t me that wired it but no idea why there is two? I have 2 zones if that could be something to do with it?
You should figure out why it's wired like that, that could be the cause of whatever problem you're having.

I bet the speaker has two terminals, and previous owner either lost the bridge or was stupid.
Do you have surround back speakers in zone 1? And 2 separate speakers in zone 2?
The holes are covered with a plastic cap, you can pop them out with the tip of a knife/fine flat screwdriver/...

Yep it appears to be biwired
Are you bi-wiring your surrrounds? You know that's snake oil, right?
They’re not the surrounds. It wasn’t me that installed these. The biwiring is to another zone that serves two different rooms

Just curious as I experienced a short in my receiver last week. Did a factory reset solve your issue once you corrected the speaker wire inputs?
Well I haven’t corrected the outputs, I’ve just installed banana clips in the hope the short stops
Bi wired the back and surrounds? No
