guys i need help understanding hrz
 

i saw a post today the guy said he hit 142.5 in his windstar at witch was a belive 67 hzr what is hzr i know its hertz but i dont know what tuned at 67 means !

means the note at which he hits highest on the termlab is 67hz.
Seems kinda high to me, but I new so what do I know:p
If ya have access to a termlab u can figure out the resonant frequency of your vehicle. Mine for example is 49hz

thats wicked ive heard of boxed being tuned to hrz by the lenght and with of the ports.

thats exactly. I tune my boxes to around 45-49hz. Seems to work alright.

well that helps me ! thanks !

for a guy with 216 posts and doesnt know what hertz means...lol.. thats just funny
