Is this likely to happen since its brother sub blew on it. or is this amp just too much for it??? kickers have lost their reputation in my case... |

Bronze Member Username: Help_2Post Number: 25 Registered: Dec-04 | You were over-driving(set the gains too high on...) the signal sent to your sub. Its called "clipping" or a squaring-off of a sine wave. When you clip a signal...youre actually sending quite a bit more power to the subs than you think. 10x as much in some cases... remember, gains are not a volume knob.... You set the gains to match the signal coming from your head unit... for example...Alpine Head Units usually send a 4 volt signal through the RCAs. so, youd want to set the gains on the amps to 4v aswell. Properly setting gains is a very good skill to learn, because it saves your equipment from an early death. |

Silver Member Username: Sploosh56Ohio Post Number: 451 Registered: May-04 | to set your gains properly turn the volume on your head unit 3/4 the way up. Then with your amp already in the lowest position on the gain slowly turn the gain knob up untill you hear distortion. Then turn the gain slightly down and you're done. |
