You are getting this when your car is turned off and you are running the system off of the battery's 12.5V
RMS power @ 12.5
140 x 2 into a 4 ohm load
and.... you are getting this when your car is turned on with the alternator charging your batteries at 14.4V
Dynamic power @ 14.4
200 x 2 into a 4 ohm load
HTH. This is a sub amp I assume?
