Is there a fuse in the subwoofer? - The Audio Players & Recorders

Yes, a fuse problem could potentially cause a lower power output from your Bose Lifestyle 5 subwoofer. If the subwoofer is not receiving sufficient power, it may result in reduced performance. Here are some steps to check for a fuse-related issue:

1. Locate the fuse: Refer to the user manual or documentation for your Bose Lifestyle 5 system to determine the location of the fuse in the subwoofer. It is usually located on the back of the subwoofer or inside a fuse compartment.
2. Check the fuse visually: Inspect the fuse to see if it is blown or damaged. A blown fuse will typically have a broken filament or a discolored appearance. If you find a blown fuse, proceed to the next step.
3. Replace the fuse: Purchase a replacement fuse that matches the specifications of the original fuse. Carefully remove the blown fuse and insert the new one in its place. Make sure to follow the correct orientation and ensure a secure connection.
4. Test the subwoofer: After replacing the fuse, reconnect the subwoofer to power and audio sources. Turn on the system and test the subwoofer to see if the power level has improved. Listen for any changes in sound quality or volume.

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.

No, subwoofers are not fused, however, amps are. If you're having a power supply issue you might check the fuse located on the amp itself, or any inline fuses that may be installed on the wire powering your amp. Inline fuses are generally mounted right next, or sometimes, attached directly to the car battery.

if a fuse does not blow when a short is present then the wire or unit will catch fire. You have a dead short most likley in the subwoofer. If you unplug the subwoofer and the fuse does not blow then your unit failed.

THE AMPLIFIER "IC" MAY BE SHORTED!
IC MAY NEED REPLACED.

The amp is blown. You need to get it in for service. No telling exactlly what is wrong untill it is opened. 215-736-8055

Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.

then the circuits took a hit and the fuse didn't do it's job in the 1st place. best is too get new circuit thats inside the sub woofer.

sorry to be the bearer of bad news

Check the circiut board for any blown capacitors. Sometimes it's that simple as replacing a capacitor. But then again, what is causing the capacitor to blow??/ Hope this helps.

do the fuses blow no matter what volume you are sending?
