Stilo standard speakers - will 4x50W be enough

[ale199020]

Hi everyone,

Just got my self a new 02 Stilo, having sorted the lighting show on the dashboard (just need to work out why the fans make lots of noise but don't blow any air now!) i'm moving onto swapping out the radio. I have a stereo from my old car that i want to put in and i just want to confirm it will be ok as i don't know what power output the speakers on the Stilo need.
The stereo (Kenwood KDC-W313) is rated fo 4x50w, will this be sufficient to power the Stilo?

Thanks in advance,

Alex
