Is this how you get a sponser?
 

The name brand i use is just an example.

Alpine HU
Alpine Amp
Alpine Subs
Alpine Speakers
Clean set up, in a nice car.

Take pics of the car with the system and send it to the company.

Is that how it works?

If it's like any other competitive activity involving sponsorship you really would need to win some high profile contests on your to get potential sponsors attention.

Also, make sure you spell 'sponsor' correctly in your proposal.

you should think hard about sponsorship, usually have to sign over your car for a year or more to tour, if you want to drive great, but if not someone else will wheel your car around the county for you.
here is a form from Weapor R for you to look at, its not for sound systems but it may give you an idea. http://www.weapon-r.com/sponsor.html
Your looking at havin to set up some sweet I.C.E. to compete or even be sponsored in todays settings.
Huge dollars are being spent even on non sponsored cars, take mine for example. a 1 1/2 year project setting me back possably 10G's or more just to have something fresh, and you got to think of things no one else has done. Its all for love, and the thrill of sitting in your car after every paycheck is spent and having some thing most people wont see exept at comp. If you got the time and $$ you can do it, but sponsors are looking for the fresh new cars to rip apart and usualy your bound by there rules and possable they'll pull it all out afterwards and your stuck with a tin can.:(
