Connected home theatre system but no sound sub woofer

Is the ohm rating compatible with map and subwoofer ...I mean are they the same all mine are 8 ohm ..I believe if they are not the same after prolonged use map channel will fail

Why not. A speaker system should work with anything that produced sound meant for a speaker.
Don't you think?
find the woofer out on the onkyo and connect the bose sub-woofer there.
Seems pretty simple. If you don't think so, go hide in a closet.
NOW!

Try differnt speakers, if they do not produce sound, amp channels may be blown and then you need to take it to a shop.

Check your owners manual.You will probably have to activate the sub woofer outlet,using the remote.This outlet can usually be programmed to do more than one function.

hi,
steps to trouble shoot for sub-woofer detection :
1. please check whether the cord is securely connected at both the ends.
2. check if there is transmission through the cord (there'll be a small static through the cord if there is transmission.)
3. reset the dvd-player to default audio-output and then choose the 5.1 sound system which is the correct setting for the th-c6.
4. also check the settings in the th-c6 whether it is in 5.1 mode(whether it includes the woofer-as it can also simple use the stereo speakers)
5. now check the sound output in all speakers by playing any original home-theatre system enabled dvd.

the system will work perfectly if the cord is in good condition, otherwise please replace the cord again, and this time check it at the store.
cheers

On the remote control for the Samsung Home Theater System look at the bottom left to a button that says "MODE", those moods change the sound each speaker gives off. if that doesn't work, you might need new wiring because there are other wires that are more durable than the ones that come with it, much better too.

I would check see if you can hear any hissing coming from the speakers if there's no sound then check to see if this product has output protection fuses and if so see if they are in tact if this doesn't solve the problem you may have dead outputs. If there is hissing coming from the speakers check your audio source to make sure it is feeding sound to your amplifier without looking its hard to say in these case's there's a lot to go wrong

This means that you have purchased a three piece home theatre system. Two tweeters and a sub-woofer. Assuming you are using a Stereo player (Tape/CD/DVC)you have to connect the Left Output of the Stereo placer to the Left Input at the back of the Sub-Woofer and the Right output to the Right input of the subwoofer by cables. Then take tweeters and connect them to Right speaker and Left speaker output at the back of the sub-woofer ( note if the speakers are marked L/R, then connect them to the subwoofer output accordingly. In case you are using a 5.1 player, then only connect the front right and front left to the Right and Left input at the back of the subwoofer. You are and you can now start playing your music or movies and and you will get theatre quality sound.
