Have an onkyo txsr501 w/jbl scs135 surround sound sys, i disconnected it to paint room and when I hooked it back up the sub worked for about 15 mins than stopped went to standby, if i turn off the sub and turn it back on it will work for a few minutes and thats it. I check the cables their good. I uplugged amp to reset any issues and still the same thing any suggestions?

Connect #1 JBL Speaker to the Front Left, #2 to Front Right, #3 to Right Rear, #4 to Left Rear, the center speaker to center and the subwoofer to sub out. This will give you dolby surround sound and individual sounds through-out the entire room like the movie theatre.

The speaker level input option is designed for receivers that don't have digital output for the sub, used this way when you set to digital the speaker outputs only get the higher range outputs so won't reproduce much bass. To get the sub to work in digital mode you need to use the digital output (single RCA) from the amp to the sub

Didn't it come with a manual?

Of course it needs external electronics to provide sound sources, controls, bass management AND amplification for the other speakers. It's just a sub.

Un plug from wall and then let it sit for 15 minutes. Pllug back in.
this sometimes fixes the problem.

I believe you have a weak ground signal. Check the ground location.
Unhook the power fuse from the battery. Remove the ground, peel off the paint behind the bolt and scrape the copper off the back of the connector as well. You want metal to metal basically. Put back in the fuse.

Could also be incorrect wiring to the subs and amp.
Has the amp ever been hooked up before?

i would say so sounds like woofer is dying unless u pull it apart and replace the woofer it doesnt have to be same brand just same size and watts and ohms then u can keep it

no sound

if you do not have the digital hook up from the tv to the reciever
then you will not get the subwoofer sounds or the dolby digital sounds
if you don't have this on your tv then just turn off the dolby digital when watching the tv , and you should be able to hear the subwoofer thru the virtual surround sound
hope this info is worth a fixya and if you need other help then just ask me and
i'll be glad to help

Hello, the setting must be "Not Activated" That is for zone 2 setup. If you are setting up 5 speakers the rear speakers should be connected to surround not surround back. Thank you Onkyo USA.
