cracking/poppng sound
Okay. Ive got a sony cdx-f7710 headunit w/ 4v preouts and an audobahn
a8002t amplifier pushing one perfomance teknique 12" icbm-5912 subwoofer. (max says 2000w and I cant find RMS so...) The a8002t i have bridged so its pushing around 800w to the sub. Now, with the bass boost switched on it still runs nice and hard, but sounds like ass because of a cracking/snapping/popping sound. any explanation? |

You are reaching the mechanical limits of the subwoofer. Try turning the bass boost all the way off and see if that helps any. -- Jethro [(Vas/Vbox)+1]^.5 * Qts or Fs ------------------------------------------------------------------------ Jethro's Profile: http://www.caraudioforum.com/vbb3/me...p?userid=18662 View this thread: http://www.caraudioforum.com/vbb3/sh...d.php?t=227958 CarAudioForum.com - Usenet Gateway w/over one million posts online! |

Sometimes a box not sealed good can cause the it to vibrate against the edges, or air leaks |
