I am very new to car audio and have tried to read up on wiring options for the SR5250 but I am still a little confused. I have a pair of SR5250s in the front stage and I am going to power them with a Kenwood KAC-X40, rated at 4x70 rms. Would it be better to bi-amp these speakers, using a separate channel for each mid and tweet, or will that be too much power? I will be using the passive crossover for now. Thanks in advance.
