different ohm speakers on the same amp

So I actually have a 4 channel 200a Rockford amp and 3 RCA outputs on the head unit. So should i wire the 5x7 co axles with the 6.5 mid range loudspeaker in parallel on the rear channel of the amp, since they are both 4 ohm, and the other 6.5 component on the front channel since they are 3ohm, and run the 4 tweeters with the high output speaker leads off the head unit? Or what would be the best way to wire these with that amp and get the most power and best sound? By the way, The sub output on the head unit is hooked up to a different amp and sub
