i own two pdx amps in my ek

PDX-1.1000 <- powers my sub
PDX-4150 <- powers my splits and rear 6x9's

they are exactly what i wanted in terms of sound. nice tight, crisp and bassy but not too bassy, if that makes sense. also great size and light weight! the pdx heat sinks are really great too..

i would recommend alpine pdx to n e one but then again.. its not only about your amp. its about the speakers your running off the amps and their quality ..

but alpine > eclipse for me.. reason.. i dont like the sound quality of my friends elcipse subs when he turns them up.. they arent crisp but i dont know what model he has.. so ya! go to an audio shop and try hear the difference..
