Jamo subwoofer SW 410 E not powering up

If your Pioneer SW-8 subwoofer is not powering on, there are a few things you can try to troubleshoot the issue:

1. Check the power cord: Make sure that the power cord is securely plugged into both the subwoofer and a working electrical outlet. If the power cord is loose, try unplugging it and plugging it back in.
2. Check the power switch: Make sure that the power switch on the back of the subwoofer is turned on.
3. Check the circuit breaker: The subwoofer may have a circuit breaker that has tripped. Check the circuit breaker on the back of the subwoofer to see if it has tripped. If it has, reset it by pushing the button back in.
4. Check the fuse: The subwoofer may have a blown fuse. Check the fuse on the back of the subwoofer to see if it has blown. If it has, replace it with a fuse of the same rating.
5. Check the auto power function: The subwoofer may have an auto power function that turns it off after a certain amount of time if there is no audio signal. Make sure that the audio source is playing and sending a signal to the subwoofer.

If none of these steps resolve the issue, there may be a problem with the amplifier or power supply in the subwoofer.

Internal power? Check fuses. No fuses? Disassemble and check Power supply if it is internal. If it is external, check power supply with meter.;.

Refer to the applicable Jamo manual.

There is a fuse under the plug, check that first.

Use the PRE-OUT SW (subwoofer) output and connect it to the left RCA socket of your subwoofer.

If the subwoofer has its own power cord seperate from the rest of the audio system, the internal amplifier could be fried or u have a loose connection inside the box

Well it would void the warrantee, but you can take the back panel off and the power supply will only have two leads (3 if grounded) in from the plug, and out to the crossover. It sounds as if you are correct that the power supply is bad.

Dual Voice-Coil
The unique Dual Voice-Coil design allows both left and right channel sound from just one speaker. Simply hook up both the left and the right channels to the special terminals on the speaker. Hook up one channel only, if the speaker is to be used in a conventional stereo set-up.
