This Alpine MRP-F450 4-channel amp is what I plan on buying to power my Polk Audio 5"x7" db570 midrange speakers with. the speakers are rated at 60watts rms so i calculated about 80 watts rms. I like this amp so far but havent heard much about it. Im going to use it to power all four of my speakers unbridged.
