They are 330w peak and 110w rms..

First question: Will these fit? Side speakers behind doors about the back seats.
Second: I don't feel my deck will provide the power to get the potential of these speakers, what kinda amp could get these kickin? I was thinking like a Rockford Fosgate punch 400s.

 

First : what is the size? That'll determing whether they will fit or not

Second : I would say get an amp with around 100-150wrms with that much power handling

 

The speakers were to big for the stock placement.. the back of the speaker ran into the material way before it was against the plate to screw it down.. luckily someone left 6X9 boxes in my garage like 4 years ago.. so i dusted them off and used them.. bought some 14 or 16 gauge speaker wire to be able to either have them behind the back seats by about 1/2 foot or to just put them in the back seats. They sound a lot more clear and loud.. but still need a amp to get the potential out of them.

 

I ran into the same mounting depth problem. All I did was trim the back end of the speaker baffle and fits just right
