Adding a Sound System

(Columbus, OH)

I have a 2007 Kawasaki ZX-10R and I want to put a head unit, two speakers, maybe some highs, an amplifier and a sub on the bike. do I need to upgrade the alternator, or generator, and which one do I have. I have researched to find out but I haven't gotten a strait answer. Where would I find a more powerful alternator or generator for that matter? Iron Pony is the only motorcycle store around me, I live in Columbus, OH. My name is Sean, and my e-mail is covell72002 at msn dot com.

Thank You for your help!!!
