An active crossover is for low level (not amplified )signals. A passive crossover can be used after amplification.
Keep pushing on, things are gonna get better.

Yes. If it's a stereo amp you can use one side for mid high and one for bass because stereo amps are basically two amps in one unit.
Quote or can you configure it so your taking the output from the amp and splitting it through the crossover ?
Do not do this. You will be sending amplified power into your crossover, which will fry it.

It is a question of voltages.

Mic outputs are around 5mV (0.005V), nominal "line" level is around 1V (strictly 0.775V, or 3V DC from a Pioneer DJM) and the speaker level can easily reach 50-100V, some big toys can make 200+V.

You can imagine what would happen to components rated for 10V max, having 100V shoved up them. They tend to "fail".

thanks guys it was one of those late night things that was frying my brain
unfortunatly the matrix ukp2100x isnt really powerful enough to use it one chanel for tops and bass, best laid plans an all that lol
 
so ill have to start saving for a  2u 4 channel amp to fit in its place ,might try out the thoman tsa 4-1300 as they seem to be well though of for a cheapie 4 channell and would have enough power till i can get somthing proper in there
 
thanks anyways guys

Why can't you just buy another amp to go with your Matrix?

just a space /compactness thing 
 
if i buy another amp then ive got to buy another rack so 3u box turns into 6u box and the extra weight its only for a simple sytem of  18" subs and 12/1 tops 
 
trying to upgrade and make everything smaller and lighter lol
