With a 12volt battery set up dropping to 11.5 volts the Crunch GP3000D Pro made 2850 watts at a 1.03 ohm reactive. That's 4 12volt batteries. If you can get the voltage up the amp will make much more. By just starting the car and using the high amp alternator (starting at 16.1 volts and dropping to 12.3volts), the 3000 made 3732 watts. That's crazy isn't it. THAT'S NOTHING! I hooked it up to a 16volt battery set up and it just went crazy! With the battery voltage dropping to 15.7 volts with a 1.4 ohm reactive this monster made 4640 usable watts. NOW WHAT DO YOU THINK ABOUT THAT! [/QB]
