i plan on using the stock back seat mounts to attach the wall securely to the car, I'll be welding a frame together with risers that will attache to the four seat mounts and i will make it even with the rear. I'll be wasting some space but i'll gain more access to the rear fuse box and some extra storage below the wall for random stuff. at this point I'll have to make a cut out of the inside of the wall for an access so I can access the fuse box from above.

You should hire a proor-reader before posting. Great business ethics here.

Yes they need a crossover, but no separates like that would require a custom made passive crossover that the design of and build of such crossover would likely be out of your comfort zone. Separates really need an active crossover, either built into a HU like the Pioneer 80PRS or the Clarion CZ702 or as a stand alone unit like the miniDSP or a Soundstream Harmony/PPI DSP-88R. The stand alones are more expensive than the HU options but offer MUCH better control of the signal. The cost will throw your budget out the window though and you would also need more amplifier channels free as everything would need to be on separate channels. Look into the Pioneer TS-D1720C components or the Crescendo CZ 6.5's or the SoundQubed QC-HF6.5's in the store to support the site. All are in your price range and decent speakers to use on that amp.
