2011 Cayman S Speaker Upgrade Issue

[drkursat]

Hello dear Cayman Owners,

 

For 3 months I've been enjoying Cayman S, but last week one of my "2" speakers was broken so I bought Focal speakers. My Cayman is non-bose and there are speaker places at the rear but they're empty. So I bought 10cm Focal speakers and 10 meters of cable for there too. Seller told me that "does your main unit has 4 outputs; other way you must use an amplifier." 

Do you know how many outputs does my main unit has?

I don't want my Cayman screwed or broken so I'm afraid to install rear speakers. Do you have any recommendations?

Thank you.
