Re: sub woofer keeps blowing fuses

NO dont try a 3 amp fuse.It is made to BLOW if there is a problem. That sub is not worth fixing, JUNK it. There are a lot of problems with it. Such as heating up and melting the board witch could cause fires. Thats what happened to mine. Like I said JUNK it and buy a different one.

Hi, we moved the sub woofer from its original position and now it keeps blowing fuses. I would like to repair the sub woofer, as it works well and is quite new. I live on the south coast of NSW...

Where was it sitting before it was moved? Did it have it have more ventilation and keep cooler? This sub has a powerful amplifier in it. If it got moved to an area that restricts air circulation around the sub more it is possibly overheating and causing fuses to blow. Put a fan on it and make sure it is on a hard surface or up off the carpet at least to keep the bottom side cool as well. Also when one moves a speaker it's often to put it into a more convenient area to be able to turn it up louder with less disturbance to others. This will draw more power and create more heat within the amplifier than it's previous location. If this is so keep it as cool as you can and turn it down every so often to give the amp a rest. The key here is to keep it cool as you can. One thing you never want to do is put a higher rated fuse in than the unit is rated for. Always use factory recommend fuse rating.

Mission m-cube sub fuse keeps blowing

If you have replaced with the correct rating and the fuse blows off then you will need to check for higher current drain in the sub woofer or the network. After replacing the fuse load up the subwoofer slowly, reduce the bass and as you increase check at the point the fuse blows off. Now we need to analyse if the rating of the amplifier you are using is rated for the subwoofer. If your subwoofer has a higher rating you can increase the rating by about 25% and check again. Some amplifiers give a very higher voltage on full bass which could result in such a condition. Moderate this and check again. If the fuse stays Ok you can continue with this new rating.Otherwise the output of the amp at higher volume needs a confirmation. Hope this helps. Good day

Sub-Woofer blowing fuses.

You should open it up and look for a short. Usually, an exposed wire is touching metal. Wrap the wire with electrical tape and look for a ground wires that are loose. That will blow fuses too.

Keeps blowing fuse in woofer

Seems like the wires inside the woofers are crossed. Open the sub and make sure that there are no bare wires touching. If everything seems OK then the circuitry inside is blown.

Bose acousticmass 15 sub-woofer making a noise

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

Subwoofer issues


The fuse blows when the current that passes through it are beyond its rating. This could be brought about by excessive consumption of the load, in this case the amplifier powering the sub-woofer.

Repairs would involve component level and require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron. Often it is just the finals that needs to be replaced. Of course we cannot discount the possibility of other components or section such as the power supply.

The smoke indicates something heating up such as a resistor or diode or a capacitor.

Should you be uncomfortable opening the unit and doing a DIY (do-it-yourself), then perhaps you need to seek the services of a qualified professional.

Should the downtime and cost of repair be no longer economically reasonable, purchase of a new unit might save you further trouble.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
