a good alternative power source for a 2 ohm final load but boner or not zenon amps are more effiecient than kicker amps the sundown 1500d i own puts the zx1500 i owned before to shame[/quotere
really and how so, cause from talking to kicker reps who tested this amp, the zx1500.1 puts out more power and is just as efficient if not more than the saz 1500. I like the zx1500.1 cause its efficient. At 1 ohm the kicker puts out 2300+ watts but is not as efficient as it is at 2 ohms. The basically put out around the same power but at different ohm loads and i highly doubt you will hear a difference in sq. I believe you're suffering from the placebo effect my friend. Gotta justify buying the sundown i guess:crap:
