Amp to 3.5mm speaker?

Yeah you are going to blow that speaker to pieces. Most of those bluetooth spearkers are meant for having a source coming from a phone. Those jacks are good for ±3V at just a few miniamps. 

EDIT: Found some more info. Some cases they are good for ±1.4-2v.

Most speakers are going to be around that if they are bluetooth. So, it would be safe to say 20v source is going to turn things into a small mushroom cloud.

My middle speaker for surround just gave out, I would usually go get it repaired but current circumstances will be putting a hold on that. In the meantime, my only space- efficient replacement is a spare speaker that can connect via Bluetooth and aux. As I understand it, traditional wiring from the amp sends quite a bit more voltage (something like 40V, correct me if I'm wrong) because it powers the speakers and they're usually of the louder variety. However, I have loads of cables I can splice to make a functional connection from the amp to a 3.5mm jack.

 

Is the voltage from the amp too much for an aux device to handle? My internet searches have not yielded the explicit result of this, I've seen quite a lot of results the other way around (people wiring aux to their speakers to get sound output from a phone or tablet) and I'd hate to waste all my time soldering and twisting wires just to wreck something.
