Also, since the Infinity tweeters come with their own crossovers and their frequency response is 2,500-25,000hz, what kind of low pass filter should I get for the midranges? I assume it shouldn't be a sharp cutoff at 2,500hz?
Sorry for asking what may be basic questions, just trying to learn.

So as far as low pass filters I have since removed the ones I got from parts express since they developed a static noise lately that went away when I removed them. So I guess they're poor quality... anyway I wouldn't recommend them anymore. So now I'm back to square one for my filtering. There are options though, first is an audio frog crossover unit here that could be used, it has a crossover at 4200hz:

Not sure about fitment they look kind of bulky.
Did some more searching though and found these crutchfield brand component speakers that they sell that comes with a crossover unit that has a crossover point of 3.5khz:

Not ideal, but better than paying double the price for the audiofrogs and the crossover itself is much smaller and would most likely fit nicely in the doors. Also you could use the tweeters as they are 3/4"tweeters with nearly identical specs to the infinity tweeters. Not sure if they play identical though. I'll bought a set though and I'll be testing them. I'll also compare the tweeters too.
To mount the tweeters in the stock locations I used one of the supplied adapters for the infinity speaker then used a thin strip around it of the glue on the dynamat (i think its butyl glue) then press it in. So far that has proven to hold the tweeters in very snugly and I haven't experienced any rattling.
Updating with more crossover options...
I'll be trying these as well they seem the most ideal in terms of crossover point and price, they're found on ebay, beware though, you want the version with a woofer frequency of 20-4.3khz, not the other version:

Ct sounds crossover, similar 3.5khz crossover to the sound ordnance crossover mentioned above, but better priced:
