So you need a stereo amplifier that will drive one ohm loads (putting the dual voice coils in each speaker in parallel).  There are other combinations.  See the crutchfield alternatives at:

Since the sensitivity is only 85db you need a strong amplifier to drive them.  At least 250 watts/speaker is best.

Good Luck.

QUESTION: ok im looking at 3 different amps but what is better to go with a 1000 watt 2 channel or a 1000 watt mono amp?]

what is the difference

im looking at

orion CO8001 ..     800 watt mono
kenwood KAC-8105D .. 1,000 watt mono
kenwood  KAC-7205 .. 1,000 watt 2 channel

Answer
Any of them are good.  Choose on features, ease of installation, looks and price.  There is little difference in sound output among them I can assure you.  However, there are differences in sound quality from amp to amp and you can not know without serious auditioning.  Maybe buy from a dealer who will let you exchange if you find, after installation the sound is not to your liking.  If you are a neo-audiophile you may not detect any sound quality differences; it takes experience and lots of comparative listening to become a "golden ear".
