Hi, i'm new here, i want to buy an amplifier to power my Prologue100 speakers, i've searched for days and found this at a good price, however, i only have one power supply with 12V 2A that may fit and i feel that isn't enough, i also dk if it must be AC or DC...
Can someone help?
 
It's an old laptop adapter, but the connector doesn't have a pin in the middle, i saw somewhere it should have a pin, or maybe idk the difference... sorry for the questions but i don't have much knowledge in this.

In case this doesn't work, can you recommend a cheap one that'll do the job? Or any adapter that's 12-24v will do?
 
I have a version of that amp, and it is quite good. Bass frequency response does lack a bit, but if you have some kind of tone control/equalization capability on your source device, it's not too bad.

You really need a 24V 3A power adapter to get the best out of that amp, something like this one. The power connector on the amp is for a 5.5mm power plug. The outer ring is negative and the inner pin is positive.
 
If you look at the picture of the power supply I linked to in my earlier post, there is a diagram just to the right of where it says 24V 3A which shows the outer ring as negative and inner ring as positive.

If you look at the third picture of the listing for the amplifier you linked to in your first post, you'll see that there is a similar diagram next to the power input connector with matching polarity. The power connector on the amplifier has a pin in the middle that goes inside the inner ring on the connector of the power supply.

If you don't see such a picture on the power supply you have, you can measure with a multimeter.

I think the Breeze Audio TPA3116 amp does not have reverse polarity protection on its power supply input, so make sure you have correct polarity.
