I just bought my 07 Grand Prix GT with the optional 9 speaker monsoon system in it...

Where are the 9 speakers... and the supposed sub??

I see 1 in the dash.. 2 in the front left door.. 2 in the front right door and 2 in the back dash... that is 7 by my count.. i dont see a sub or a 9th speaker... Am i missing something here?

oh ya and my front left door speakers arent even working haha.. GM will be fixing that
