can all amps run at either of these rates?? and what determines which one u are using??? because if this is possible for all amps then i can gain a bit more rms at 4 ohms
most amps run off 12 to 15 volts. it depends on your car. the higher the voltage the more wattage you get outa your amp at 14.4 volts my amp puts out 175 watts rms and at 12 it puts out 150 watts. my car has a volage of 13.9 volts so i am actually getting somwhere in between those wattages.
