Can I please get the Model Numbers
of your television and sound bar?
Generally your subwoofer can hook directly to your TV using the included White/Red cable and hooking it into your television.
On the back panel (or it could be on the side) you should see an option for Audio Output.
In rare cases there are HDMI passthroughs but these are generally for high end systems.
Another possibility is using an Auxiliary Cable
which is similar to a headphone jack (3.5mm) on both ends. You may only need to hook this into your device and usually televisions only have Audio Output
with this connection.
If you have any further questions feel free to message me.
I've included a links to Amazon
in case you need to order the cables which are super cheap, or you may pick them up at a local retail store such as Wal-Mart or Target.
Hope this helps!
