I have 2 of these subs and 1 of them keeps blowing fuses. as soon as i put a new fuse in and plug it in it blows. do you have any ideas why and how i can fix it. im good with a soidering gun and specs. thanks for any help you can give me......eddy

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.
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
The fuse is a protective device. Fuses dont blow unless the amp ( in your case ) is drawing too much current. DO NOT put a bigger fuse in. Obviously, there is a problem with the amplifier inside the sub. If the sub is under warranty, send it in for repair to an authorized warranty depot. If not it's not under warranty, then take it to the authorized warranty depot anyway. Why ? because they will have the schematics ( electrical diagrams ) to troubleshoot the unit quickly and it may be a common problem. If it is a common problem, the factory may have released a modification and possibly it could be covered under warranty under a factory 'goodwill' program. Good luck. Rob
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.
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.
