Hey just curious how you guys would work a frequency crossover rack mount into a rig. is it possible to do with one amplifier? or would i have to use a computer system to do that?

What would you be using the crossover for? A cross over just splits a full range signal into two non full range signals, one below the cut off and one above.

What are you aiming to achieve from splitting your signal?

i want to send lower frequencies to my 15in cab and higher ones to my 4x10 for a better overall performance and sound out of my rig

A 10" speaker is still a relatively big speaker capable of a serious low end response. Definitely not a good choice for a dedicated high frequency driver. Mids, perhaps, but definitely not highs.

Cannot be used with a single Amp. One needs at least a two channel power amp.

4x10's tend to be better at handling lows than single 15" drivers.

For better sound, put the 4x10 on the bottom, 1x15 up near you ears.

Or sell one and get another matching cab, so you've got 2 15" cabs or 2 4x10" cabs.

There are two ways of organising a crossover, you can have one between the preamp and the amp (you'll then need two amps for the split signal) or you can have a passive crossover between the amp and the speaker. This isn't likely to prove successful though in improving your sound without a lot of design work. The easiest way to beef up your sound by splitting the signal would be to add an active sub from a PA system. In any case a 10" speaker isn't the best to go for as you have been told earlier.

Actually neither 10 or 15" speakers are bassier, it depends upon which 10 and which 15. 4x10's often sound bassy because they try and copy the ampeg sound. In fact most of the bassiness of the typical 4x10 is the result of natural rolling off of high frequencies rather than any extra bass.

Mixing speakers of different makes or sizes tends to wash out the character of both speakers so you might want to consider matching cabs in your stack.

and when you match the cabinets the Cross over becomes pointless in many respects.

The standard cross over point between a 8x10 and an 18" W-Horn loaded CV was 60-100 HZ, so in all reality, this is all about a Subwoofer, an earthshaker, so get a power amp an a horn loaded sub.

A preamp, an active variable crossover, two powered cabs (1x15 2x10) using power amp modules from the likes of these (http://www.bkelec.com/) and you're cooking.
Start crossing over about 110-120hz.
My Ashdown RPM1 preamp has a variable crossover and variable balance between low and high.
