quick voltage question

hi

i know this is a VERY subjective question with a lot of variables, but lets say i have a mono d-class amp for subs. the rating, not benched, says 2400RMS x 1 @ 2ohms at 220A. now if my alternator was weaker and only puts out 130A, how much less would that 2400RMS drop to percentage wise, assuming 2400RMS is REAL power if the amp was connected to a 130A alternator??

thx

wattage would drop around 35 %, if it was 2400 true power, you would get around 1400-1500 actual out of your system. but maybe think about an alt. upgrade, takes power to make power

I wouldn't even install it without a larger alt. The rest of your vehicle needs power too //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
