To determine if you have the right wiring for your car speakers, you will need to do the following:

1. Identify the wire connectors on the back of your car speakers. Most car speakers will have either a positive (+) and negative (-) terminal or a set of color-coded wire connectors.
2. Locate the corresponding wire connectors on the wiring harness for your car's audio system. This should also have either a positive (+) and negative (-) terminal or a set of color-coded wire connectors.
3. Compare the wire connectors on your car speakers to the wire connectors on the wiring harness. If they match, then you have the correct wiring for your car speakers. If they do not match, you will need to use an adapter or modify the wiring in order to properly connect your car speakers.

It is important to note that car audio systems can vary significantly, so it is always best to consult the owner's manual or a professional if you are unsure of the wiring in your vehicle.
