I'm trying I'm trying to make Bluetooth speakers. I spliced auxiliary cord an splice speaker cord there is four tiny wires and 2speaker wires how do you wire the 4 wires into the two wires which ones are which ones are negative it's like red gold green blue an they're tiny
What speakers are these?
If these are self powered speakers then the BT receiver connects to the input of the amp which might be the four thin wires not to the wires that go directly to the speakers themselves.
If they are passive speakers you will need an amp with BT receiver to convert them to BT.
