I just recently set-up a 5.1 system with a Onkyo sr606 and rti10's as my two fronts. I was looking for a bit more power out of them and was wondering if bi-amping them with a seperate amp would help improve this. Also, how to go about it, the crossover filtering and whole setup of a bi-amped system was confusing to me. Should the reciever run the higher frequency and then the seperate amp run the lower frequency. Any help would be appreciated.
