So if your headunit runs active you can theoretically use y splitters on the headunit’s mid Rca channel (assuming you’re going to set your crossover/eq the same for all four of those 6.5’s.) Then just grab a smaller amp for the tweeters. Disregard any of that if your plan is to use a dsp.
However, if you want to run all six speakers on one amp you may want to consider using these instead for that kind of power

Two wired parallel to 2 ohms are rated at 250 watts rms so at 300 rated per channel on the amp you’ll have a little extra. Those speakers models you inquired on call for 500 per side in the same wiring configuration brought down to 2 ohms and your amp will only be putting out 300 (per channel)
those tweeters call for right about what that amp is rated (192 per channel) at 4ohms since those are 4 ohm tweeters
