Need amp suggestion

I don't know anything about peak power, frequencies, rms or anything so maybe you guys can help me choose an amp that will pump my speakers. Right now I have MB quart rsd 216 components in the front that is only powered by the HU right now and sounds pretty crappy right now. Power Handling: 60-120 watts (not sure if this is rms or peak) Impedence: 4 ohms Sensitivity: 2,0 watts (90 db/1 m) (whatever that means) Frequency response: 38-32.000 Hz X over frequency: 2500 Hz Crossover slope: 12/12 db/octave For the rear Im probably getting the CDT cl-6x slim coaxials. * Sensitivity: 90 dB * Frequency Response: 60-20,000 Hz * Recommended RMS Power: 40W * Peak Power Handling: 80W * Impedance: 4 ohms From these specs can you guys help me choose an amp with the right power to push all 4 speakers. I don't need to know a specific brand, just the rms, channels, etc. Thanks.

I would go with either this Alpine MRV-F340 or Alpine MRV-F450dream it, build it, fiberglass it
