i have a fender Fm212R Guitar AMP with a preamp jack. It comes with 2 x 12" speakers at 50 watts each (giving a total of 100 watts of power) However the back of the amp says #360 Watt [im guessing 360 watt peak]. The amp also has a slot for A preamp to be connected if i get a 360 watt preamp, will the sound's compasty be at 360 watts of power without damaging any of the equipment?
