u can eanny 1.5 volt battry ,get 2 length wire .strip both ends.stick 1 strip end in the speaker box on positive or red connector .then you do the same on the negetave or black connector .now you should have one strip end for positive one strip end for negetave now connect negetave to battry .then brush the positive wire to battry positive .if you hear a thumping sound that mean that your subwoofer is good if you dont hear eanny sound that mean it is dead.i have done this for the past 50 years.bye..
Fuses only blow like that when a semiconductor device is acting like a piece of wire causing an overload. An ohmmeter on the ohms setting will show any transistor with this condition as a short, just like you had touched the test leads together! Follow where the fuse leads to. And look out for signs of damage too. The most obvious parts to go are the ones that do the work, in the power supply or the main amp device, often an IC.
You can tell a lot from what the blown fuse looks like. If it's all black or even shattered, it's likely a short circuit somewhere. If it's just blown, then you have an overload.
Another way to find out is by figuring out when the fuse usually blows. If it blows when it's tapped, shaked or moved then you have a loose wire that's touching somewhere it shouldn't.
If it blows when you turn it up high, it might just not be able to handle that much power. Remember to ALWAYS turn down amplifiers when you hear noticeable distortion. Or, the sound pressure from the speaker might be jostling things inside the cabinet.
If it blows when you plug it in/ turn it on/ start using it you've got an electrical problem, not a mechanical one. You'll need to get the multimeter and start tracing faults.
a black fuse means really excess current.if it is the ac mains fuse be careful.i am is 120 watts of power different.if it is the dc fuse,try a slow blow fuse with the same rating.
it will allow more dynamics from movies ect.
This particular product has a lot of comments posted on it and I've answered a few of them now so I'm beginning to think you may want to look into weather or not the manufacturer has received any complaints or this is just a freak occurrence. Keep in mind not all commments are the same so this may just be nothing. Either way I can tell you this much, if fuses keep blowing quickly, over and over again-You have a direct short somewhere and will most likely be in need of professional assistance of some sort with the possiblilty of having to replace it. I'm sorry it's not an easier fix but it may not be too expensive.
The first thing you can do is go to www.retrevo.com to download the manual. Secondly all you have to do is match the colors of the wires to the imports in the back. You have five speakers. Two have gray wires, two have red and one has blue. If you also notice each speaker has two wires. One a solid color, the other striped with black. For instance, put the solid red wire into the red import and the red wire with the black stripe into the black import. Repeat this with all the other wires. The easiest way to hook it up to your computer or laptop is to take one of the aux wires (the wires with the yellow/green/black tips). It doesn't matter which one. Put into you headphone import on your computer or laptop. Then put the other side into the Aux on the subwoofer. Located on the front. Turn on the power on the back. Then hit the aux button on the remote. That should work....
