Speaker Questions (Alpine)

I have Alpine Type S 6.25" speakers in the doors of my Civic and Alpine Type R 6"x9'' speakers in the rear deck and i was wondering if anyone knows if they should be run off of a 2 channel amp (one channel for front and one for rear) or if i should buy a four channel ( one for each speaker) or do i even need to put an amp on the 6.25" Type S up front?

Type S 6.25'' - peak 200W
Type R 6''x9'' - peak 220W
Panasonic Deck 50Wx4 (peak) about 20W rms

Thanks for the help!

get a four channel that puts out about 50-75 watts rms per channel, should have your speakers singing.
