how would a Clarion DXZ955MC sound instead of a Kenwood MP828 that I have? Will there be a big difference in SQ? I saw it and played with it at my local dealer but cant compare with the Kenwood, they dont have both..
Are you powering your speakers with the amp in the deck? If you are there might be some SQ difference, I'd probably give the Clarion the nod in that instance.
If you have external amps in your setup the difference in quality of the line-outs will be pretty slim.
