Pauly1987 Posted April 12, 2013 Report Share Posted April 12, 2013 So I've noticed for a while now that my subs Kicker l7 15 2 of them in a 12 cube box powered by a zx2500.1 My subs after about half way through a hard hitting song will seem to lower in volume (it will no longer be ear throbbing bass) So today when that happened I powered everything off and felt the dust cap, it was warm but nothing to be alarmed over! I know the amp is happy as my volts stay above 14.2 while driving Am I just pushing the subs too hard with power and its not liking it after a while! If I let them (rest) for maybe 15mins and crank it up it hits hard but only for half the song maybe less? Link to comment Share on other sites More sharing options...

Guest Posted April 12, 2013 Report Share Posted April 12, 2013 whats your electrical look like? 2500rms is a huge load for a stock electrical. dropped voltage = quieter. dropped voltage = blown amps. Link to comment Share on other sites More sharing options...

Guest Posted April 12, 2013 Report Share Posted April 12, 2013 are you measuring voltage at the amp terminals? Link to comment Share on other sites More sharing options...
rockFord_Expedition Posted April 12, 2013 Report Share Posted April 12, 2013 What are you using to measure voltage and where is the measurement being taken at?
