Everything looks like its installed correctly, but no sound. The PC say's it's "good to go"? I just disconnected my working speakers and woofer to install these two Bose, whats the problem?

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.

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

good day sir, there is a chance that you PC audio port is also busted( the green port) you may use the blue port, but you should enable 4 speakers (usually rear speakers) on your volume comtrol properties , (or 6 speakers if you want to use the pink one). If still no sound on all ports, buy a new PCI sound card. Coonect it on any available PCI slot on your PC. then run the CD device driver.

You have 3 choices - 1. the speaker is blown, 2. the wiring is broken or disconnected, 3. No output from the amp.
If you have a VOM, an inexpensive one wil work fine, and can get the speaker connection, set the meter to 1K, hold one lead against one speaker post and tap the other post, if the woofer cone moves it's not the problem. Connect the wires back to the speaker posts and then disconnect them from the amp. Hold one probe against one wire and tap the other - if the woofer makes a sound then woofer and wires are good - take the amp to the shop or buy a new one.

in the Denon setup under speaker configuration set the sub to LFE+Main

what is the problem in details what all have you done

was it working initially when did the problem start

If you are using the speaker out wiring (not RCA) then disconnect all speaker wires. connect only one speaker or use a known good test speaker. Try each of the 4 speaker outputs. If none still do not work, then it sounds like a blown output chip which will need to be replaced.

the board that you are talking about is the crossover, does any of the speaker work the woofer or tweeter or midrange drivers? If the woofer does not work then take out the woofer and take the wires that attach to the speaker on the back and hook them directly to the speaker that you took out if it plays you need to replace the crossover in the speaker, this should be easy, just call the company that makes the speaker and order a new crossover, you can do this also with the speaker if there is no sound when you hook it up direct.

Sounds like the woofer cones are blown, no fix for that except to replace them.

You did the right thing disconnecting one at a time. Are both speakers doing that? It is a little strange that both would go out at the same time, but stranger things have happened.

If you have an extra speaker laying around someplace that you know is good (even a home stereo speaker), try disconnecting both speakers and connect the one good one to see if it sounds OK. If it sounds good or at least normal, you have some bad speakers. If the one speaker still sounds bad, you have a problem with the speaker wiring someplace. You might even need to run new wires just to rule them out as a problem.

If the problem is not the speakers, then this is a very strange problem indeed!
Good luck and I hope this helps you. If you need more help just reply back after you checked them out a little more.

Since there's been no response in over a month, I guess I'll assume the problem was fixed!
