I bought new speakers because my right driver side front speaker gave out. I have Polk Audio DXI 650's. Where the hell do I twist tie the cables from the door to?

 

Im sure there are wiring diagrams on here somewhere, you have to tap into your stock wires that has the harness on it and the terminals on the speaker indicate which wires go where, which kind of system does your car have? Need more info on your car.

 

The speakers should have came with wires, on the end of those wires should be connectors, if you look at the terminal for that speaker(the part where all the wires are soldiered) from you pic it looks to be the left connector is + and right is -

 

you connect to the little tabs sticking up. the smaller one is neg with the larger being the Positive.
