Anyone any idea what size the speakers are in the bravo?

I had a sub and amp in my Punto...and I am seriously missing the bass! So because the integrated stereo in the Bravo doesnt have a pre-out (correct me if I'm wrong), then i will need to fit some components to try and get some decent sound again!

So anyone any ideas?

Did you know about the built in graphic equaliser in the i.c.e, you can adjust from rock/jazz/preset/classic/and customer which is the one you can use to change to your own sound quality, not forgetting you also have the loudness option to add more bass, plus the treble and bass settings on top of that also, seems a shame to start pulling bits out of the new bravo, i know everyone has there own preference to there type of sounds and how loud they like to play them but just seems a shame to start pulling bits out and adding third party substitutes so soon, also will this effect your warranty should something go wrong with the sound system after things have been changed.
Of course this is only my opinion,everyone to there own.

Correct me if im wrong, but is there not an option to have a higher spec stereo with Subwoofer etc as a factory fit option? I'm sure I read a review on the new bravo whereby they guy was commenting on the ''brilliant'' stereo with 6 speakers and a sub...
