they have a power handling of 100 watts (300 peak). I have 2 sets of them and i'm looking for an amp to drive them. all the 4ch amps i see put out more than 100 watts, but would it be less with all 4ch hooke dup and not bridged?

basically i'm looking for some reccomendations for an amp to drive these component speakers. as you might notice, i'm a novice with this car electronics stuff.
thanks
