help chose between 2 amps

[irondiezl3]

so im finally going to be running an amp to my speakers. i have all new speakers mb quart all the way around. my question is the speakers handle 60w rms and there is two amps i can use. both are identicle inside and out except one is 80w rms and ones 60. initially i thought go with the 60wrms but then i thought maybe i can get away with 80wrms im assuming i wont have to worry about overpowering them since im sure ill lose some of that wattage through all of the wiring by the time it hits the speaker. theres only 25 dollar price difference between the two. so help opinions on which power to chose welcome.
