• Answer:

  William has a point. But First off 1. are they new AND 2. Rated at the power you are giving them? 3. properly connected? obvious answer here first is the amp gain. you probably have it set high. too high. or one of the following is the culprit. 1. if so, see 2. If not they may be damaged goods and cannot handle the power being thrown at them. possibly cracked drum and / or / and/or surround, and/or damaged spider (diaphragm of cone) 2. if not, they may be under driven - check gains on amp 3. assuming new here, check polarity (-) to (+) I'll end with the fact that u need to read an online guide on how to set your amp gains. remember, burn music or have it stored at optimal bit rate like 320kbps to get the best sound from your music. this makes the highs so beautiful and lows deep and hard! for older music u can hear the bass more as you just turn it up more (when setting the amp gains you'll learn this) use test tones for the best optimal sound and proper setting for all music. if test tones recorded at low bit rate, below 270kbps, then set the volume LOWER than 75%. say 60%. then adjust the gains form there. download from here: http://www.ronelmm.com/tones/ another great site for overall intro's on speakers, subs, amps, walk thrus, etc. http://www.caraudiohelp.com/
