Pin 1 is Negative -numbers are molded in at the OEM speaker connector.

Buy these at your dealer and don't cut the OEM wires:

so I bought a pair of polk audio dxi 400's (4inch) my question is how do I wire it up. im using the exsisting speaker wire as I am not doing an amp just a straight swap. . the oem speaker wire is split into two wires. blue/black and blue/brown. . my question is which one is the positive and which one is the negative. .

also is it best to solder the wire to the new speaker as I cant use the standard speaker wire connector??
