Need help connecting all speakers. Is it possible with adapters?

[shmike1]

I got a new sound bar for Christmas, and wanted to hook it up to an old set of speakers and a receiver that I had. I want to at least hook it all up to my PC, and possibly the bluetooth if it works through all speakers. This is what I have to work with:

Vizio Soundbar w/ bluetooth (can't find model name)
It has digital, optical, sub out, red and white RCA jacks, and a 3.5mm jack which I think are for inputs.
Two big Jensen speakers from a long time ago (they have only speaker wire output)
A PC of course
And an Aiwa av-d30 receiver(The link shows a pic with the connections on the back of it):

Is there a was I can connect all of this to either the soundbar, PC, or receiver? What adapters would I need if it's even possible? Could I connect the speakers to the soundbar and pair it with my phone? I wish for all of them to work as one speaker on the left, the soundbar in the middle, and the other speaker on the right. Also, I'm sorry for being such an audiophile noob. Thanks!

Soundbars are meant to be on their own - not to drive speakers, this is what your Aiwa is for. So, you have two "sound-producing" devices - one is the soundbar (with optional subwoofer, it seems), the other is Aiwa + Jensen speakers.

Keep them separate. Use this soundbar for your guestroom TV. Get a center speaker for your Aiwa (it is 5.1 system, after all). If you want to pump music from your phone - there are $20 Bluetooth receivers all over Amazon/eBay.

You can use a speaker to line level adapter to convert the center speaker out of the Aiwa to an input for the sound bar so you can use it as a center speaker. Connect both the left and right speaker wire connections of the adapter to the center speaker out. Use the red and white rca jack if they are labeled inputs. If not then use the 3.5mm stereo jack.
The Jensens connect to the L/R front speaker connections on the Aiwa
Connect the PC to the 5.1 channel input on the Aiwa
Add a bluetooth receiver and connect it to the Aiwa aux input for your phone.
If you want to hook up your TV it would depend on what audio output your TV had so you might need an adapter.
Set the receiver up for 3.0 since you have no sub or rears. You can add a powered sub and unpowered rears later.
