Hi! i just moved and I took apart the computer sound system my ex had set up for me, i labeled the cords but in the move they kind of came unravelled now i have no idea how to set it back up!!! it is a yamaha system with two speakers and sub woofer
Most likely the sub has the crossover in it, most likely the 2 input cables from whatever device you want to play through the system will plug into the sub then the 2 speaker cables will come out of the sub and go to the speakers, just be sure to have everything connected into and out of the sub and make sure the power cords for the speakers and sub are plugged in, I am assuming this is a self powered system wich means the amplifiers are built into the speakers and sub.

Stereo systems have 3 wires, of which one is common for both the speakers......first check for the wires and when you find it, plz connect the negative of the two speakers to the common and connect the others to the rest two wires.....
Sound system speakers have standard polarity which is indicated either with a "+" or a "-", or with Red and Black colors near the speaker terminals. This same polarity marking is also found on the sound system amplifier section. Most speaker cable has a polarity indication; either color coded, or a physical difference in the wires. Reversed polarity results an obvious decrease in bass, and a hollow sound in the mid range frequencies. If your speaker cable has no obvious polarity indication, you can check the polarity as follows; connect a 9V battery to each speaker cable for no more than about a second; long enough to see the woofer cone move. When the + battery terminal is connected to the + speaker lead, the woofer cone will move out. When you have this situation, label the positive speaker lead, either with tape, or by tying that wire in a simple knot. Make sure both cables are checked.
After you swivel the center latch, press down on the two plastic latches on either end (in the same crack) with a flat head screwdriver. Make sure you remove the knobs used to adjust the base and LFE levels. Now you can push the plastic cover back about a 1/4 inch and then lift it off (I used a flat head screw drive to pop it off - took some effort). Inside, remove the 2 phillips screws from the top of the green circuit board, unplug the board, and push the 4 plastic holders out of the way so you can flip the board over. Replace the 3 amp, 250 volt fuse.
I haven't tried putting mine back together again yet. I'm off to Radio Shack...
I am assuming this is the message that shows up from your receivers front display panel? It could be the receiver is telling you that you may have the neg & pos. wires crossed and in the opposite position either in back of the receiver speaker posts, or in back of the speaker terminals themselves. My Yamaha receiver has this nice feature where it will tell you when the speakers are "Out Of Phase" which describes the problem I have described here.
Just go back and make sure your wires are hooked up correctly, and use tape and a Marker to label pos. and neg so they will be easier to hook up next time you have to move the system, or decide to change some aspect of your system. I would then take the time to label every wire that goes to each speaker that you plug into the back of your receiver. This a BIG time saver........
Sounds like the hum might be mains hum caused by the failure of the power supply capacitor(s) in the sub. It/they will be the largest on the pc board. You will find all the details (needed to replace it) on them. If you find more than one replace both.
the very best way to solve your problem, go to the electronic store and ask a dc power supply adapter 15volt 2A,vice versa polarity. with universal connector for it sure you can select the right type connector do you have for it fit to the back socket of your unit. before you connect read the correct polarity of your device you see label at back (+, -). and set the polarity output of the adapter correspond to your unit,,,
