wilcox_81 Posted April 4, 2012 Author Report Share Posted April 4, 2012 I have an 06 impala (not the exact same as yours but...) my car res freq is around 47 I would 1.0 turn the box around 2.0 seal is off 3.0 tune higher (in the 40's) I am tuned to 44 now burp at 46hz and do a 147.7 sealed on dash 4.0 seems like a lot of voltage drop to me (but I am fussy I dont like below 13 volts LOL) 5.0 how did you set your gains ? 6.0 test and tune (seat position,vents,visors... ) 7.0 you meter with your seats down right ?

wilcox_81 Posted April 4, 2012 Author Report Share Posted April 4, 2012 sealing off forward from the trunk helps alot..getting the sound into the cabin toward the meter... I would get with 412CVX about a box design to get the most outta your space...he does some badass designs also deaden as much of the car as you can...as well as test flipping your current box around to face forward..even though its not sealed off from the trunk to see if it meters any better than the last time you had it done...its all trial and error to get more db's if your not adding power, more subs or even upgrading electrical to get maximum power outta your amp sealing off forward from the trunk helps alot..getting the sound into the cabin toward the meter...

Guest Posted April 4, 2012 Report Share Posted April 4, 2012 Btw you can't measure resonant frequency with a ported box. What you're thinking of is "peaking" on the meter. Link to comment Share on other sites More sharing options...

ALPINE408 Posted April 4, 2012 Report Share Posted April 4, 2012 ya they told what your peak hz was for that box not what your cars res freq is the only true way to find res freq is to get a sealed 10 and play tones on a meter and the loudest tone wins (is your res freq) Have you ever had your woofers blown?
