Im not gonna spoon feed you son. Ive watched some very intelligent people give you great advice which you chose to ignore so im not going to waste my breath.

hey jeremyc thats ok I probably deserve that!
ya know to tell you the truth I have no clue what the anwser is
Thats 1 thing that I dont anderstand is all that 12 db 18 db 6 db stuff !
but heay Im young and I will learn as I go I hope!
well I just wanna let ya know something, I got rid of 1 of those 5 channel amps and GOT NEW SUBS (rockford fosgate p1 10")
Iknow Iwas gunna get the p2 but since that 5 channel amp (that im stuck with) can handle those p1's just about right.

We all started somewhere, and then we learned. The site mentioned before will teach you anything an audio enthusiast will ever need to know, plus you will see some of this electronic stuff in high school and college (i know reading up on car audio gave me a head start in physics) So you may not have a clue right now, but do some reading and you will soon find out and be much better off

X-overs simplified.

There are 3 aspects you need to know. The x-over point (or freq) the slope and if its high or low pass.

High pass allows higher freqs to pass through, low pass allows lower freqs to pass through.

For example 80 Hertz 24 db LPF (low pass filter)

The x-over point is 80 hertz.

The slope is 24 db an octave. An octave is 1/2 or double the current freq. So an octave down from 80 is 40. An octave above is 160.

Since its a LPF we are concerned with 80 and 160 hertz.

So at 80 hertz you have a cut off of 3 db.

One octave above 80 you will have a cut of 24 db + the 3 db you lost at 80.

So at 160 hertz your music out of that speaker will be 27 db quieter that it was at 79 hertz.

HPF is just the opposite. Your music would be 27 db quieter at 40 hertz that it was at 81.

6, 12, and 18 can be simply be substituted for the 24.

6 db an octave isn't recommended for a tweeter in a high power system because it doesn't roll off sharp enough.

12 db an octave rolls off fast enough that it limits the speakers excursion as it drops in frequency.

Thats why I said you couldn't use it in place of a dedicated x-over for those kicker tweets.

thnx for sharing great job +rep

what the hell you selling? That is a copied and pasted answer from the previous home theater thread.
