If the car stereo is rated for 4 ohms:
- Bridging: You can bridge the two 16-ohm speakers, which will connect them in parallel, reducing the overall impedance to 8 ohms. Bridging is typically used to increase the power output of the stereo, but it can also be used to create a more "full" sound by sending the same signal to both speakers. However, bridging should only be done if the car stereo is specifically designed for it, as it can damage the stereo if it is not able to handle the lower impedance.
If the car stereo is rated for 2 ohms:
- Series-parallel: You can wire the two 16-ohm speakers in series-parallel, which will result in a total impedance of 8 ohms. To do this, connect one speaker to the positive terminal of the stereo and the other speaker to the negative terminal. Then, connect the positive terminal of the first speaker to the negative terminal of the second speaker.
- Bridging: Bridging is not a good option for 16-ohm speakers connected to a 2-ohm stereo. This is because the impedance would drop below 2 ohms which could damage the stereo.
It's important to note that wiring speakers incorrectly can damage both the speakers and the stereo, so it's recommended that you consult the user manual for your car stereo or seek advice from a qualified car audio technician before making any modifications.
