i heard you play sine waves (30hz-60hz) at moderate volume and see which ones the loudest

it is usually right about where everything starts to rattle that did not rattle before

what if it all rattles already because of previous systems?

Go get NCH Tone Generator

It's free, I believe

most cars are around 40hz i think i remember someone saying that on here once before. i know my car did great with a 48hz tuned box and i figured my car freq. out to be around 45-50hz so i'm building a ported box for my DD's to around 45hz to peak around 48.
