those are my speakers, i have 4 db570's rated at 60 watts rms and 180 watts peak, there is a power accoustik amp 4 channel for about one hundered and its 70 watts by 4 channels. i know its better to overpower your equiptment than underpowering it. does the peak being 180 have anything to do with how much i can overpower it? for example if i had speakers 60 watts rms and 100 peak would i want to overpower them less as if i had 180 watts peak? or does it just not matter and should i not overpower them at all? anyways if you have any suggestions on 4 channel amp brands for under 200 it would be helpful, i was thinking maybe alipine but i am unsure, and i belive polk overcharges on their amps.
