Have you ever tried to install your speakers or an amplifier into your car, but got a frustrating message that says “No device detected”? If so, you’ve run into problems with the connector and mounting mechanism in the radio — it’s called a “poe switch din rail mount.” These are often tricky installations, but if you follow these tips, you can get your problem fixed quickly.
The problem
When installing speakers or amps into cars with DIN-style connectors (like in Chrysler products), some cars don’t detect this type of connector and instead gives an error message when trying to use it. This is due to a wiring failure and requires either fixing or replacing the connection cable.
The solution
If you are using a mounting mechanism (such as the MBUS-01 or MBUS-02 from Scosche), you must ensure that the wiring harness is properly connected to your device in order for it to be detected with industrial ethernet switch. This can be done by either:
Running additional wires — connecting the existing speaker wiring to the connector’s speaker output wires. Splicing another speaker cable — connecting an additional speaker cable (one with a spade lug on both ends) so that it connects with both wiring harnesses. Soldering — if you are comfortable soldering, this is one of the best ways to make a clean, permanent connection.
If you are using a different mount, you may have an option of connecting the speaker wires directly to that. However, this is not recommended because even if your car detects it and plays a sound, it will likely be quiet as compared to using a separate speaker cable. You can also try using a temporary wiring harness (such as the Beltronics PINK-01 from Scosche) which works with any mounts by simply removing the “screw-on” part and plugging the wires into that slot.
Regardless of whether you use a screw-on mount or a separate speaker cable, you must ensure that the wire is connected to the correct wiring harness. If you have an amplifier that requires 12v power, there will be two wires on the speaker harness for power: one for positive and one for negative.
Conclusion
These tips should help you resolve problems with your speakers or amplifier being detected in your car. If possible, always connect your amp’s outputs to the wiring harness so that it is detected. If you’re not comfortable soldering, consider running an additional wire from your speakers to a different connector on your amp’s wiring harness. If this is not possible, use a temporary wiring harness.
