SOURCE: After I transported Labtec APX

Open the unit and look forr the fuse to the unit. If power comes to the sub woofer drive board , check for the rail voltage to the IC.
Check the resistance of the subwoofer, make sure it i working.
If supply is coming to board, check for any signs of crack on the PCB. If not check for any loose connection on the IC.
If posible use a good soldering iron to solder suspected points in the board and the IC pins.
Since your set was working we must use the logic to look for a fault that occured during the transit.
if all the tests prove corrrect, then we can suspect the IC.
Make sure that there is input audio signals to the IC before you can confirm.

Do i have to have the sub-woofer in order for my logitech X-230 speakers to work with my computer?


Certainly any large speaker itself cant be used with
very weak computer out signal
The signal should have power amplification in addition to
voltage amplification to energise large speakers

MX6050D Subwoofer Issues


Hello, welcome to Fixya!

Fault is either from the main system or the sub-woofer itself.

You need to test both unit in order to detect which of the two is giving the fault, so that you can concentrate on the faulty unit.

Test the woofer with a AA battery or any other battery. Put your ears close to the woofer and observe if you will hear any sound. If the woofer makes sound, then it means the woofer is working, but if it doesn't make sound, then it means the woofer is defective. Or you can disconnect one of the working speakers and connect the woofer to that part. If there is no sound, then obviously, the woofer is defective.

If the woofer seem to be working, then the unit needs to be tested also.

Connect one of the working speakers to the sub-woofer's section of the main unit. If the speaker doesn't bring out sound, check the system's menu settings, check the volume and make sure the sub-woofer volume is raised to the highest level and not on mute. ( Note that most Theater systems has separate volumes for each speakers). If the volume is raised to the highest level and there is still not sound from the woofer part, then it means the woofer channel has burnt. It could be a fuse or a defective channel. At this point, I think you need help from a repairman.

I hope the above is clear.

Regards.

I need a wiring diagram from car stereo to 2 x 6 " x 9 " and a sub woofer please


You can connect the two 6x9 speakers to the two individual left and right outputs of the car stereo.
Connect each of the left and right channel with the correct polarity . Now the Sub-woofer requires an amplifier to be connected separately and so you need to use the car stereo to be linked to a sub woofer amp which powers the sub woofer.

I have a Fisher RS-909 Surrond Sound amplifier. It has no "sub out" jack. I had the sub-woofer working in the past by wiring it as shown in the manual. The problem is that the system was in...


Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

I have a rockford fosgate 1001d and 2 audiopipe dvc 12s need 2 know how wire speakers


Check to determine if your sub woofers are DVC 4OHM or DVC 2OHM SOLUTION 1 If your sub woofers are DVC 4OHM then, from the positive (+) of the amplifier run your cable to the positive terminal of voice coil 1 on sub woofer 1 then continue to connect all the positive voice coils together on both sub woofers. Do the same for the negative from amplifier to all the negative voice coils of both the sub woofers. RECAP: all positives together on the positives and all the negatives together on the negatives. This will give you a 1 OHM load to the amplifier making it deliver all its power but will also run hot. So if you are living in a hot climate take care. SOLUTION 2: Connect the negative on voice coil 1 to the positive of voice coil 2 on sub woofer 1 Do the same for subwoofer 2 now you should have a free negative and a free positive on each of the sub woofers. connect the free positives together and follow through to the positive on the amplifier. do the same for the free negatives sending them to the amplifiers negative. This will give you a 4 OHM load to the amplifier. Not full power in this mode but the most stable working condition for your amplifier. SOLUTION 3 If your sub woofers are DVC 2 OHM then you only have one reasonable wiring solution. Connect like solution 2. This time because of the DVC 2 OHM sub woofers you would have a 2 OHM load to the amplifier. This is also a stable load for the amplifier and does not generate to much heat and still deliver over 50% to 70% of the amplifiers power. good luck and drop me a line if you still have doubts. dreamsystems

your sub woofer has only one input to make it work. plug in your rca cables into the back of the sub woofer and the other end into the audio out or subwoofer out put on the back of your surround system.

Go to the following website www.servicemanuals.net where you can get the service manual for $17.00, unbelieveable, don't you think? The service manual should help you sort out your hookup problems. Good luck.
