Hey Randolfo - Thanks man, and sorry I didn't answer your questions till now, they slipped by me somehow.
With regards to the question about disabling the internal amp the answer is no, it's not possible.
I might be wrong but I think it has to do with the design with the active crossover and DSP.
But the question is - why would you ever want to use an external power amp when the active CLR has an extremely high quality power amp build in that is part of the tuned FRFR system that is the CLR ?
As for your other question, I find most that chicks don't have a clue nor dig gear, but the CLRs are different, as you can put your foot on one of them and strut your package
