If anyone is good with setting up the cut off freq. help me out here please

Here are the specs for my speakers: (There in my sig)

Fronts : 53-21,000 Hz

Rears: 30-30,000 Hz

Subwoofer:28-1,000 Hz

Here are my options in the head unit for the fronts:
50 - 63 - 80 - 100 - 125 - 160 - 200 (Hz)

Here are my options in the head unit for the rears:
50 - 63 - 80 - 100 - 125 - 160 - 200 (Hz)

Here are my options in the head unit for the subwoofer:
50 - 63 - 80 - 100 - 125 - 160 - 200 (Hz)


Any help would be really apreciated!

Thanks alot...But may I ask why? I want to learn about what im actully doing and why im not setting them lower or higher etc

80 is usually standard for subs and you want to paly all freqs avail so setting the mids the same would allow that (or close)

80hertz is where bass really starts getting heavy. too much for most 6.5" speakers and most speakers that are made to play any kind of voice... thats why you set the HIGH PASS at 80, to take out the lower bass...

some ppl like to go with alil higher cut off (100hz/125hz) in the rear just to have some filler sound back there...

and the sub. it is not made to play any type of voice, or any higher tones... and to have a smooth roll off with your highs, you set it the same...

thats not true with ALL speakers. some higher end 6.5s and whatnot can handle the lower bass no problem, but 80hz is a good starting point for it all

So noob question, the lower the hz the higher the bass? So If i was to set my fronts to 50 I would be sending more bass signal to them? Im not going to do it because I like how it sounds now, I just want to understand how this works

The more bass you send to your mids the worse the distortion at higher volume levels.

No, Yes. lol Its not "higher" like volume, its more like "lower" as in octave, frequency. The lower frequencies are the bass notes (like below 80). The 6.5's are really not designed to effectively reproduce low bass notes, so you "filter out" the low notes sent to them using a HIGH PASS filter (ie, lets high frequencies pass).

Subs are only designed to play these low frequency bass notes, so you "filter out" the high frequency notes by using a LOW PASS filter (ie, lets low frequencies pass).

So in short, you send the high notes to the speakers that play high notes with a high pass filter, and send the low notes to the speakers that play the low notes with a low pass filter. A general starting point is 80hz for each but like I said, that's a starting point. I have mine in the cobalt crossed at 100hz. It's a personal preference thing that also has to do with the type of sub and enclosure, and the acoustic characteristics ("cabin gain") of the car.

basically sound goes from 0HZ (hertz) all the way up to infinityHZ... people can hear from 20hz to 20k hz... though the average person can only hear about 28hz to 18khz...

the lowe the hz, the deeper the bass... kickdrum= between 60 and 80hz... voice= somewhere around 800-1200hz i believe...cymbal=1500hz-3500hz. and so on...

bass from 80hz and lower is 'nondirectional'. meaning that its hard for your ears to pinpoint where those tones are coming from.

i said to set the fronts at 80hz Highpass because thats usually a good start to keep some good midbass up front (like some drum hits, bass guitars)...
and 100 in the rear just because you want most of your sound to come from the front... when you go to a concert, you look at the stage, right?
