I have a 94 firebird formula with 10 speakers system. Is that considered a monsoon? If not what is a monsoon?

Also I need to replace my front speakers and it seems that it is a 6.5. Is that correct?

What size are middle speaker and rear speaker?

 

So I take it you found your answer? Seeing as how you posted a link to Houston F-body on that other topic....

And you can't get throw a pair of aftermarket speakers in place of the monsoon speakers. That would be too easy....

 

Not Monsoon unless it says Monsoon on the deck.

 

cool thanks
