wait a minute why would i need to know the speed of light, do u mean the speed of sound, if not that would explain why my calculations seem a little off

Welcome to the club, I'm an audio head hear, check out my cardomain. Always thought it would be cool to goto school for ICE. Are you a SQ guy or SPL?

jachin- why you need to know, just curious.

Wonder where my compass reciever is, it was NOT thrown off with my install. must be different than pre +00'*

Geez, those 00+ with the battery location, and the compass now sound great for stereos, save the factory harnessish thingy. Hell just run completely new wiring anyways.. for EVERYTHING

He probably gave the speed of light because most students in physics and engineering do all our math in terms of the wavelength, frequency, and energy of light. Very few curricula in the engineering sciences perform calculations based on the speed of sound (partly because it is so variable).

The speed of sound at standard atmospheric pressure (1atm, or "sea level") and standard CO2 concentrations, 68F (20C - standard room temperature), and zero humidity - is 347.43 meters per second.

okeman'* formula is correct, but instead of c being the speed of light (which is 299,792,458 m/* in a vacuum), replace it with the speed of sound, which in this case, I'll use 347.43m/*.

Therefore, you have:

w = c/f
w = 347.43/80
w = 4.3429m


So jachin, your calculation was correct. (an aside - if you were an old-fashioned scientist, you'd round off to the correct number of significant digits and arrive at an answer of 4m).

If you want the answer in feet, multiply that answer by 3.28. Therefore, the wavelength of an 80Hz sinewave, in feet, is

4.3429 * 3.28 = 14.25ft.

should have asked that i could have made this alot faster lol
anyway goodluck and what mid-base do you plan too use
and what size i was lookin at redbarons set and it looks like you can fit an 8" mid base driver in the rear 6x9 hole with a little work of course and what kinds comp. set u wanna use
