My klipsck kw-100 subwoofer will not power up i,v checked fuse it,s not blown want migth i do next

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.

Hello,
If you plug in the subwoofer do you have power ? If the answer is no, you can check the power supply. If you have power but no sound, then check audio amplifier (probably defective audio IC).

i dont know if amp has fuse for each channel, but they would be easy to see.. otherwise that baby has a blown component or two on a pc board, maybe an output power transistor of capacitor failed.
Last time i went to a shop it was like $100 plus parts for a similar repair.
I recomend sending Sony support an email and see what they say before you take it anywhere as well..

If fuse has been blown means power capacity of the subwoofers exceeded the actual power transmitted.Subwoofers capacity cant hold on to the actual power transmitted.If you replace a new fuse check first if internal circuit was not damaged .When a fuse blown out its an indication that something wrong happened within the circuit.Check first subwoofer line if there was short circuit using a tester.Select OHMS mode and try to check both lines.If no movement it means you have it check to a service technician to fix.

Most likely the fuse for the radio is blown. If the radio is factory, check the interior fuse box (normally located on the lower drivers side of the dash) for any blown fuses. Normally the fuse that will blow will say something like "Radio", "Audio", "Interior", or "Cig" near them. If the radio is aftermarket, check the fuses noted above and also check for a blown fuse located on the rear of the radio (Usually next to, or on the main power harness).

It is NEVER a good idea to increase the values of fuses . Chances are you have internally damaged your amp. The next time you are faced with this problem you need to find out why your amp is blowing fuses and not keep changing the value of the fuse.

Actually, there is a fuse. You need to take out all the screws and remove the two dials so you can take off the panel. Look to where the power cord connects to the board, and you will see the fuse. It is a 125V 4 amp fuse.
