What size cvrs? Really hard to answer with out more detail. If they are 10's or 12's i'd say with some custom box building you could make them work easily. You might need to do some modification to the back seat. Building a nice custom box to fit a certain vehicle isn't always either. And I dont think you really need 6 cvrs in a monte carlo. Four will do you just fine and finding an amp to power them all will be much easier. Sell the other two to make money for a 4 channel amp. Just my 2 cents worth, hope it helps.
