You’ll need to clear up what speakers you do have. There are no Sonos 2 speakers. Knowing which actual speakers you have will help us hone in on what to suggest to you.. 

Sorry  sonos 1

I assume you mean a ‘Sonos One’.

Also does your Turntable have a Bluetooth Transmitter (Tx) too?

Anyhow see below…You will need to use a Sonos product that has a line-in, or if it has Bluetooth, a Sonos product with a Bluetooth Receiver (Rx), as follows…

• Port/Connect (no BT Rx)
• Amp/Connect:Amp (no BT Rx)**
• Five/Play:5 (gen2) (no BT Rx)**
• Era-100 (has BT Rx) (requires additional dongle)**
• Era-300 (has BT Rx) (requires additional dongle)**
• Sonos Move 2 (has BT Rx) (requires additional dongle)
• Sonos Roam/SL - has no line-in, but has BT Rx only

** Note: If any of the above compatible devices are used as a HT Surround, then their line-in port and Bluetooth Rx both become disabled.

Once the TT is connected it can play to any/all Sonos products - a line-in connection is the recommended/preferred option.

Here are links to the two Sonos adapters that are currently available to use (if required):

This next link is also worth reading as it supplies a lot of good information about using a Turntable with Sonos speakers…

No blue tooth on the TT.  thank you for the answers

The TT comes with an RCA cable.  im looking for an adapter that connect this cable to the sonos speaker.  is that the line in link that provides that.  the RCA cable has two prongs (left/right) and a ground connection

You ‘likely’ need an RCA (female) to 3.5mm (male) audio cable, or adapter, but this of course all depends on what Sonos product you purchase for use with its line-in port.
