I would not run the tweeters off the HU.
Buy a 4 channel amp.

People have their opinions about amp's, But I would go with an eDesign audio amp. http://edesignaudio.com
They get good publicity, and they aren't too expensive. However, I don't own any, I've been using Almani Audio because the quality and the price fits my budget.

run all 8 speakers off of a single 4channel? I looked at it... their mids/highs amp seems a bit strong for running these? I'm just a little sketchy about using a brand I haven't heard of.. not that they are bad, they look good. I'm looking for something that will be a good match power wise to these speakers... thanks for the info.. i'll do some research on their amps and see.. anyone else have any suggestions or does everyone agree with foci fosho?

you can run 8 speakers because of the cross over.
Essentially each cross over is a channel, that's why I suggest a 4 ch amp.
like the Nine.4 amp which is rated at
4 x 65 @4Ohm
4 x 100 @2Ohm
2 x 150 @4Ohm
