monsoon?

My wife bought a 2002 Sunfire coupe and I am planning out the sound system to put in it. How do I know if it has a monsoon systme in it or not? I see that it has 6x9s in the back and what liiks like components in the front. Thanx

Does the head unit say monsoon on it?Another thing to look for is the monson amp,it's back in the trunk on the drivers side behind the interior trim carpet towards the top of the quarter panel.
