If you're dead-set on the monsoon system, I'd recommend skipping the dash speaker, since you don't have a hole for it. Morad's got a Monsoon amp in stock right now. Those are like $300 new. I realize that the monsoon setup involves no thought to pair up and you could pick up the parts used from Morad cheap, but you're better off researching a bit and going after-market. The Monsoon setup is only like a half-step better than what you have, totally not worth the labor.
