Sub Woofer does not work

blown speaker or x over

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

Hi, I went to the Denon website and they have no documentation there for your receiver.
But do not frown, I have some good suggestions for you.
0 Don't beat the dog. After all, it's their job to chew things.
1 Get a new, un-chewed cable and see what happens between the sub output and the sub woofer. If it works, your in business. If it does not work. Don't be discouraged . Go to step #2
2 If the sub output on the Denon has failed, and everything else is good. There is another way to use your sub.
Install a patch system using the Headphone output from the front of the Denon. It may seem odd, but it works exceptionally well for the following reasons. It works on all signal sources. So if you are not playing a home theater source, you still have the use of your sub.
You will need the following adapters.
1 A Male stereo phone jack to female mini-phone jack. (Something that would accept typical small headphone sets such as those on an iphone).
2 A stereo "Y" connector that that has a single stereo male mini-phone jack that has two "RCA" female jacks.
3 A simple RCA male to male stereo cable pair as is commonly used to connect CD players, etc. i.e. separate red and white RCA connectors at both ends.
1 and 2 above may be available as a single unit combined with each other.
Take these adapters and connect the Item 1 into the Receiver, Item 2 plugged into Item 1, Item 3 plugged into Item 2 and finally the other end of Item 3 plugged into the two female RCA jacks mounted onto the back of the sub-woofer. If the sub only has one female RCA connector, get a RCA "Y" connector that has a single male end to 2 female ends.
This setup will work perfectly with any sub. The reason is as follows. Most decent subs have an adjustable high frequency cut off. So you can vary it from about 20Hz up to about 140 Hz.
I recommend that it is cut off at 80 hz. This way the bass transition is usually seamless between the woofer and the rest of the system. .
Then adjust the woofer volume control in a similar manner.
If it all works out, give the dog a treat and enjoy yourself.
I really hope this helps, I love my sub woofer as well.
Let me know how this turns out.
If you have any questions please post them on the site and I'll get back to you ASAP.
Best Regards,
Mark

You will need an amplifier or 2 channel receiver. Hook the sub out rca jack to the rca inputs on this new amp or receiver and hook the speaker terminals on sub to speaker terminals on same amp or receiver. Your Yamaha receiver doesn't have any power for a passive sub.Just pick up any old fairly high powered receiver for fifty dollars and you're good to go.I use old dolby pro logic receivers as they are a dime a dozen today. Good luck.

The problem I have found is the contact glue between the back panel and circuit board inside the sub woofer. The glue becomes conductive after some time (2 years..!!) and needs to be scraped away from across tracks, you can tell the problem areas as the glue is pale yellow but goes brown and conductive over time. Good luck.

It is based on your sub-woofer type..whether powered or passive sub woofer..
Assume that you have powered one..RCA sub woofer jack is the best to feed it ..you should use RCA sub woofer output on your receiver as well..good luck

Does it work when you have music on? not all movies are going to make the sub work. it depends how the video is formatted.

first check the settings of woofer or dvd player (keep in 5.1 mode and RAW)

mail me clearly about the problem,

The only thing you do is to open your receivers,then locate the output connector if you see the female RCA jack ,then push it out the broken piece ,that's it

I have a JVC sub woofer SP-pwm 505 can I use this with any system my receiver has RCA jacks it looks like this uses a S cable...is there a cable that would convert "S" cable from sub woofer to an RCA output jack in receiver [email protected]
