Eclipse is one of the best headunits out there period. the reason why is the 8v our 5 volts at a very low 55ohrm and none of those decks can do that so none of them have great sq ,
dont get me wrong the alpine and kenwood are good but clarions are garbage sorry bro i dont want to make you made but its the truth
your stereo is only as good as your head unit that is the brain of the operation...
know the only time having a deck like a kenwood our clarion is if you add a eq witch will take the voltage from that instead...
