Octavia mk2 stock speaker output

I'm sure someone has asked this I've just bought a skoda Octavia I have various questions but most I've found an answer to,

But I'm wondering what the stock power output is for the speakers I've checked model numbers ect but cant find the overall power let alone individual speakers rms output.

I previously had a Ford focus mk2 and the Octavia doesn't seem to be nearly as impressive so I'm interested in upgrading the sound system, stereo and speakers.

Not a massive problem but I've got it in my head and cant find an answer. I've been blown away buy the upgrade and am finding myself very quickly becoming a skoda fan after I thought I'd never move from Ford.
