Speaker Wiring

This is the first time that I try to install speakers in my car. Wondering if anyone can help me out........ Does the wiring go (+) (+) or (+)(-) ??

im not sure i really understand but here it goes. There always needs to be a ground in an electrical circuit "-" for it to work. If your just replacing the factory speakers then one of the wires will be "+" and the other "-" usually red is "+" and black is "-". It should not matter what way you wire them to the speaker.

hope this helped.
