I have been running 2 of the infinity reference 1230ws on my jbl 1200.1 and they have held up just fine. I just replaced them with 2 perfect 12.1 and was wondering if it would be advisable to change my wireing configuration. Would it be safter for the subs to be wired in series so they get less power? 600 watts rms a peice is a little rough and i definatly dont want to blow these wonderful speakers. Anyone got any input on this?
