well, the thing is. i have the 4 passanger version, there is no amp. i think thats why those charts dont match with my car. for example, my Rear Right speaker has two wires, blue/white and blue/orange. so my guess was that white was the negative, as thats the standart. would i be able to notice the sound differance, so i could flip the cables?

https://www.installdr.com/Harnesses/DCP-Wiring.pdf see if this helps...I don't know for sure. The only wires that CANNOT be hooked up incorectly are costant, switched, and illumination (dimmer) Get these figured out first with your meter. -------------

well all fixed, i figured out that my multimeter can tell positive/negative volt; aka polarity. so it turned out to be simple, thanks for the help.

if the signal is simply going from the HU through the existing factory wiring it should be simple. The white striped wires are positive. Any black stripe is negative
They would still play, but some speakers could be 'out of phase' from each other.
This means that when on speaker moves 'forward' the other speaker moves 'backwards'
