Why Does It Have To Be 50hz

[Eskii]

And yeah, go Australia!!

How many of us are there on SMD???

Use the resonant frequency of your car to level match gains. If you dont know it then 50hz is a good choice but it doesnt "have" to be 50.

.....and higher frequencies do NOT draw more current. Higher frequencies = less current.

Okies, i'll let ya have a little victory.

But get back to me after ya finished high skool

Oh dear, he's a stubborn one. Well, grab an amp and go for gold. Figure it out yourself. I've done it, I know what happens, but I wholey encourage you to destroy some drivers and trip some circuit breakers in the name of science.

Cheers,

After reading 3 or 4 posts, I stopped.

So I dont know what you figured out yet

Indeed, the 50hz is correct when you ise

standard AC meters, what have the best

accuracy at this hz area.

If you use True RMS and good meters

(Fluke i.e.) you can use any frequency.

Or if you use an oscilloscope.

But it has nothing to do with Music range or so.

It CAN be helpful also, but the main reason

is the accuracy of the meters.

the only reason i put that it takes more power to make a higher freq tone than a lower one is it takes more power to drive a speaker faster than it does to move it slower, and an amp does is take a dc current and convert it to an ac current at a higher amprage to a alternating freq, its just physics, and yes it does take more power to do a higher htz tone than it does a lower htz tone cause when i had my other 15's in my truck when the bass hit high notes the lights would dim but i could play low bass all night long and get no dimming at all thus for more power to make a higher freq than a lower one, thats why most sub amps are class d and mids n highs are class a/b and thats why class a/b's get hotter cause it takes more current to make higher freqs than it does lower ones, i hope i made myself clear im not a noob at this stuff cause ive seen it done in electronics class

Couldn't help it, this post is full of untruths and fail.

Have you ever heard of impedance rise? Put a multimeter across the terminals of a sub in a box and then sweep a 20-80hz tone through it and watch the impedance go all over the place. So, as Mick said, at 35hz you might have 30 ohms (nominal impedance means nothing!) and thus very low current whereas at 80hz your impedance might be very close to nominal, thus allowing much higher current to flow. More current = Higher resistance across wires and batteries = greater voltage drop = lights dimming.
