I don't think the difference in sound quality, if any, would be noticeable. I love the PDX amps though, mostly because of their size and stackability.YES absolutely...Kicker is not known for sound quality where Alpine is and the PDX's are no exception. They sound great, are small, run efficiently, and put out a good amount of power. I don't know what you Kicker is putting out but I am sure it is comparable in watts to the alpine. If it is then the PDX should be an improvement in SQ as long as you have a good deck.
