I recently sold most of my cabinets and now only have a Goliath Jr. III 8 Ohm cabinet. I previously used a SM400S with a Goliath Jr. III cabinet but typically ran the SM400S stereo with a 4 ohm Jr. III (250 watts RMS @ 4 ohms). Using the 8 ohm Jr. III with my SM500 stereo (one side 150 Watts RMS @ 8 ohms) doesn't have much punch or headroom. Since the cabinet is rated at 350 Watts RMS I would think it would be safe to run the SM500 bridged (400 watts @ 8 ohms) as long as I don't really crank up the amp. If I keep the master down on the amp does that really limit the potential wattage output of the amp or can the amp still produce wattage at dangerous levels in order to satisfy instantaneous peaks? Opinions please!
