Which amp to run Jl audio stealth boxes for bmw e46?

JL Audio 250/1 or JL Audio e2150?? The manual reccommends the 2150 but with the 250/1 i can turn the gains low and it will be more efficient because its using less power, is this right?

Since the manual says which one to use, why doubt it? I have a 500/1 and a 300/4, great amps. I think their new design is different in that it changes power output when you change the ohm load (like most amps do) while their / series amps put out rated power throughout different ohm ratings, which makes it safer and easier to know what power your putting out, even with different speaker loads.
