Beckett Posted April 30, 2009 Report Share Posted April 30, 2009 my battery voltage is only 13.8 volts for some reason (may well be because it's an old stock battery) my old car battery was always at 14.4, when setting the gain does the formular need to change becuase of the lower voltage? 100 x 4 = 400 square root = 20 volts. is that still the target voltage i'm lookin for when settin the gain? for my 100 rms..

J00bles Posted April 30, 2009 Report Share Posted April 30, 2009 that should be all he needs. i used this chart last week to set my gain and i noticed much clearer and cleaner bass. not to mention my chances of clipping dropped down too. 8 DC Level 4 M2 15s2 DC Audio 5ks26^2 clamshell tuned to 30hz9 Kinetik 1400sMechman externally reg'd 340 S seriesin a 99 Jeep Cherokee Click to see J00bles' Youtube Channel Link to comment Share on other sites More sharing options...
keitare Posted April 30, 2009 Report Share Posted April 30, 2009 http://www.harborfreight.com/cpi/ctaf/disp...temnumber=90899 I have that dmm what setting to i use to set the gains Subs are like titties, They need to come in pairs because ones and threes are just wrong, and larger amounts will always draw a crowd, we all have our favorite sizes, but the bigger ones are more fun to watch move.
