Default Noob needs help building enclosure / x-over

A friend of mine gave me a pair of beyma tweeters T2030 and a pair of 5MP60N for helping him rebuilding his car engine. The problem is that the only combination that i found when i googled about this speakers is an active crossover wich i'm unable to understand and build. So, i'm asking for help / directions on hou to build a crossover for my setup wich will be fed by chipamp's lm1875. I would also need tips on an enclosure for the speakers...

I'm not a guy with a background on electronics but i'm a quick learner, as long as it's a simultaneously explaining and building process.

Sorry for my english, but it's not my native language.

Linkwitz active filter cook book:

Linkwitz circuit boards. Op-amp power supplies are properly biased, RF low-pass circuits are included in feedback loops where possible, the layout is good.

Linkwitz Pluto electronics. 2-way LR4 cross-over, notch filters on both outputs, all-pass for time alignment, Linkwitz Transform on the woofer, shelving low-pass on the woofer for baffle step or dipole compensation, LM3886 for the tweeter channel, bridged LM3886 for the woofer, power supplies.

The above pretty much covers crossover and box design.

You might want to add a bass unit (or two) if you do not want
to build a minuture. With the two drivers bass will be restricted.
