I can' t answer on the Orions....But I did extensive testing with two Kicker KX 2500's vs 1 Goliath.......
2 Kicker KX 2500's beat 1 Goliath by .7 dB on a consistant basis. No protect issues, no over heating. But I just thought I would share my results with Kickers to help give you some feedback.
so they can take it all day @ .5 ohm? Thats cool. What do they push @ .5 ohms? Can 2 SXs handle what they deilver @ .5 ohm? Please let me know. Thanks.
