I looked them up and they only handle 60 watts rms, I am more along the lines of 100 watts rms, the speakers I have in there now say they handle 85watts rms and I can get them to start popping from overload, I am afraid to blow the 1652's. I had a set of JBL power's in my old car on the same 4ch amp and I blew the crossovers with it so this amp is nothing to shake a stick at, I just don't want to buy these and not have them able to handle the power....
