I know the link takes you to DAR. It takes you to a link which tells you how to connect your Alexa to your HiFi which I presume is what you meant. Connecting it to an amplifier alone would be useless.
I am assuming it is an aux to phone rather than an alexa I will need?
the amp/speaker is what my neighbour uses to play his guitar Zaz so im thinking it has to be a speaker?
I think I have confused amp with speaker to be honest ( what do I know) so I am looking for a connector between phone and speaker, I will follow Zacs link , I remember it being an aux, red and yellow to speaker with a 8 mm jack to phone, would that be right?
