well, you cant drop them in w/o some minor modifications. for the tweeters you're going to have to make a little baffle and use the flush mount hardware to mount them snug. i used an 8"x10" (~1/8" thick) piece of plexi ($1.94) and a dremel to make them. it can be kinda of a **tch to use plexi as it is very brittle and and cracks easily. i will post some pics of the pair i have made so you can get an idea of what i am talking about.can you just drop the 6.5" comps right in the front door? If so i think i'm gonna go with the PG RSD's too! I don't need perfection.. just something way better than what i've got.
as for the midbass driver... you're going to have to make baffle to mount them correctly. unfortunately the people at ford like to use 5x7 speakers, so baffles are a must. i will prob make the baffles for the 6.5's in the next couple of days, but it's pretty straight forward; im going to use either 1/2" or 3/4 " mdf and then from their just follow the tutorial below to properly deaden and install the midbass;

... and i've never had components before, but from what i hear they make a worlds of a difference (with an amp of course)
