I would like to know if I can safely biamp RF-35 with the Trends Audio, T-amp or Super T-amp the "poor man's way". That is, using one amplifier for each speaker, without touching the passive crossover. This should result in a somewhat higher power output and handling of the speakers. I know that if the ground is in common between the two cable posts then the mentioned amps WILL die miserably, as they are already bridged. So, does anyone have this vital piece of information? TIA
