How to connect this system to phone

[xyz123]

Hi, I am not very knowledgable about speakers etc so please excuse if this is stupid question.

I have Onkyo CS 245 which I am hoping to use more.

Most of the music I play is via YouTube music. Can I somehow connect this onkyo system with phone via Bluetooth? It has two line in at the back labelled "R" and "L". I know there are Bluetooth adapters available but not sure if it will work on my case..

Alternative is to buy something like Sonos but they are around £150 so just thinking if this there is another option.

Thanks

A BT receiver should work ok, you just need to get the right cable with connectors to suit the Onkyo. There are lods on Amazon.

If your phone has a headphone jack, or lightning connector, you can connect with a lead. 3.5mm jack to RCA phono.

I have been using one of these for a few years with my home hifi. Works fine.
The leads connect to either a headphone socket or the L & R phono sockets on the hifi.
I expect there are some newer versions now.
