So I have two hacked XBOX controllers, and an ipac

The ipac is already hooked up to my arcade controls

How do I make it so that my hacked xbox controls AND ipac are both hooked up to my arcade controls?

i am assuming that you just cut the cord and replaced with a usb and are using xbcd.  To get it to work in mame just enabled the joystick either in the command line or the Mame ini.  Then just remap the controls in mame (press tab).  You may have to change the options in the xbcd to either make it act as a joystick or gamepad, although I am not sure.  I just tried it on my machine and it worked ok.

 I'm not really asking how to get them working with a computer, I want my 360 to use arcade controls. But I also want to use my arcade controls with my computer. So I want to know if I can have both hooked up to my buttons and joysticks at the same time.

you should be able to just double the wires and it should work fine, or skip the ipac
I use the my hacked wireless 360 arcade controls for xbox llive arcade and use the pc dongle for it with mame

well I have to keep the ipac controls in there cause I've got a dreamcast ipac adapter and I'm waiting on a Wii version as well
