Hi guys,
I received a set of Wharfedale Glendale 3 XPs and want to figure out how to make them work via bluetooth (I’m a total noobie!)
I bought this as I thought it was the right thing - https://www.amazon.com.au/dp/B08M3KX523?ref=ppx_pop_mob_ap_share
Now because I’m absolutely clueless with powering speakers, how can I power the speakers without accidentally burning my house down?
Thank you so much for your help guys!

- It says for use with amps up to 50 watts per channel, but then it also says maximum input 40 watts DIN, so to be safe I’d want to err towards 40?
- What kind of power supply should I be getting? My current inkling is 19V but I’m not certain of the current
Thank you so much for your help guys!
Well first we need to know the speaker impedance, and how big the room is. With 19V supply the maximum rms voltage the amp can produce (with a sine wave) is about 13.4V, which into 6 ohms produces 30W. At the 24V max rating that would be 17Vrms and 48W. The latter would peak at 8A current draw from the 24V supply for both channels, at 19V that would be about 6A peak current draw. However real speakers aren't ideal and may pull more than that.
For safety the rule is buy a branded certified power supply, not some cheap rubbish from eBay/AliExpress - a lot of that stuff is not certified and you have no guarantee its safe at all.
Look at a wire gauge chart to size your speaker wires, the rule is the speaker wire should be able to carry the maximum rms current for the speaker - though we are talking quite low power here.
