X Over Question

I have been trying to read up as much as i can on this new hobby of mine.
I want to be as knowledgeable as possible before i take the plunge and spend money.

My question is this:
What use are the 3 cross over settings(high, mid, low) in my head unit if most amps that i see already come with built in X Overs???
i dont quite get it.

Thanks
Jazz

the cross overs in amps tend to be very simple ones with very linited adjustability. They are usually 2nd order(12 dB/oct) slopes, and have a limited range of x over frequencies. The units in most higher end head units such as your 9833 are very high quality, with many adjustable parameters. To get a better x over you would have to get a dedicated signal processor, such as the pxah-701, or something from audio control, Rockford or any number of aftermarket high end audio companies.

So this means that the X-Over in my Amp and the X-Over in my headunit will work together in harmony or will they be working against eachother?

^^no, you use one or the other. Normally, if you have x overs in your head unit or in a processor, those would be used. There are situations where you may want to use both in order to create a band pass x over, or as an additional function (subsonic or infrasonic filter to curb ultra low frequencies from being reproduced). My suggestion is to set all amplifiers to flat or off on the x overs, and use the head unit's x overs. As you get more experience, you can screw around with everything...that's what we all do on here...and it never ends!
