i doubt you can find a KX 2500.1 now, most of the KX series are gone. replaced by the ZX2500.1.
depends on which one best fits your needs. the ZX has max output at 2 ohms i think where the Orion will max at 1 ohms and will work at .5, but only if you have a killer charging system and be careful with the gains. KX has max output at 2 ohms too. kickers won't work well below 2 ohms.
i'd say the kicker's are more underrated then the orions, but not totally sure.
Kickers are built better and put out more power by at least a few hundred rms. A kicker can be ran down into 1 ohm without any problems but you better have a great charging system. The KX will be more exensive but has a better build quality, active cooling and just plain puts out more. The ZX line puts out a little more than the KX but in my opinion is uglier, lol. Polo..
Well see my plan was to run 2 treo SSX 15s on two kicker kx2500s. My treos are dual 2 ohm and u say that amp can be ran at 1 ohm with out damaging it right? You think this would be a good setup or would the orion be a better choice because it can take 1 ohm all the time?
