Hello!
I bought a subwoofer speaker system and it is a box closed.
Its wires has the same color. With an 1.5v battery I can easily identify their polartity, but for it I need to open the box that is welded with glue and I dont want to open the box, because it can be damaged.
How can I identify what is the positive and negative wires?
Is there another way?
To help me I have a professional digital multitester.
Any tip?
