does anyone out there know what the resonance frequency is for my buick grand national? im sure it is the same as a monte carlo, regal, cutlass, grand prix... from the output of my test tones it seems to be fairly deep compared to what hit the hardest in my 92 firebird. Jmac i heard u da man for this so lemme know whats up...
