Power 12.5 VDC
2 Ohm Load 1000 w x 1
4 Ohm Load 500 w x 1

Power 14.4 VDC
2 Ohm Load 1500 w x 1
4 Ohm Load 850 w x1


how would i get the 14.4 power?

(mtx 8100d amp)

 

You would probably need a cap to stabilize the voltage and then a bigger alternator cause after all the accessories take thier power youll probably have some where in the middle between 12.5 and 14.4v.

 

12 volt is when the car engine is off and it's all from the battery.

14.4 is when the engine is on and the power is being supplied by the alternator.

But like 97teg said, with other electrical stuff on, it drains that a bit. I could see this very well with my old 1 farad cap with digital top voltmeter... It's still usually always above 14 volts when the car is on, but will dip if your stereo is on a high volume and the bass hits really hard....

 

yea. 14.4 is the voltage when the car is on the alternator. but that number is not steady at all. ive seen my car at high 13s before. h:

 

A good alternator should maintain a constant 14 volts... its when electrical things start up when you get voltage drops... I monitor my voltage, and only when I get a large bass peak or I turn the lights, fan or something else on does the meter drop below 14 volts.

 

the MOMENT the lights get turned on...or while the lights are on?

 

when you first turn the lights on... it takes more power to start the bulbs, than it does to keep them lit... same with the heater fan and cooling fans...

an alternator SHOULD maintain 14 volts... if it does not either you have too much draw on it (probably too many aftermarket lights or amps) or its on its way out.
