Hello everyone!
Tv model: jvc lt-55ue76
Subwoofer model: Basscube 8S
Soundbar: Vizio 38" 2.1

Here's my problem:
I have the soundbar hooked to the tv via optic cable and it works. I have lost the subwoofer that came with the soundbar (Bluetooth). A friend gave me a basscube 8s (powered) subwoofer. I have tried hooking the sub to the tv and to the soundbar via RCA and can't receive a signal to the sub. I thought maybe the SW was defective but tested it with my receiver I have for another stereo system in the house and it works just fine. Any thoughts as to how to get signal to the subwoofer?
Thanks for listening!
 
Solution
You can't unless the Vizio has a sub out jack, which it does not. If you want to use the sub with speakers, you need to get a receiver to connect it to.
