Your question is just way too general... Which speakers exactly are you talking about (please post links) and please define "problems"?

I still don't know exactly which model speakers are they but it sounds like it wouldn't be enough power for so many subs. I also would advise against mixing various subwoofers of different models due to bad sound quality of the whole system as a result of the non matching subs.

Ok that make sense. Here are the specs on my yorkville 15"  one is the yx15, 300 watts @ 8ohms, and the other is yx150 400 watts at 8 ohms. How do I connect both these speakers to my xti 4002 amp without causing damage to the speaker or damage to my amp

If it's a passive sub and a full range top per side, I'd think it will be OK, if they're all 8 ohms.

The amp will be just fine, to get decent sound quality you'll need to run the subs on one channel and the tops on the other. The amp will see 4 ohms per channel (still not sure which subs you have?) which is not that problematic for it. This configuration would limit you to MONO content (great for live, not so good for DJ) but you have the onboard DSP to configure crossover points easily. So, which music type you run through the system?

Well, the 1004 is both 1400W continuous and 5400W peak, these numbers have different usage implications, make sure you know the difference, take power compression into consideration and figure out what is the usable figure for you...

Here's one for you to read:

I'm not sure I understand your question so I hope I get it right if not feel free to correct me :)

This is a very powerful amp so you need to use the onboard limiter to limit the 6002 to about 800-1000W with long attack and release times, this way you can operate these subs on the 6002 with relative security that you won't damage them. You can also use an external limiter with peak and continuous settings which make configuration a little easier. Also you will never want to clip this amp.

Thanks for the advise on that and that article was very helpful. I have another question I am planning on linking a 4002xtiamp and a 6002xti amp together  would I need to purchase a crossover, or can I just built in crossover that the amps already comes with

No, you don't need another crossover, the crossover in the built in  DSP is of good quality so nothing more is needed.
