I've had a ton of people ask me how I did it, so I thought I'd post some pictures.
First things first, I use 5050 SMD RGB led strips that I cut to length.
I use these plugs;

So, I take the speaker apart, drill a hole through the speaker surround between 2 of the screw holes, this is so you can route the LED wire through the hole.
Affix the LEDs along the inside of the xm9 grill;

Drill another hole in the pod, about an inch from the clamp collar, this is to run your 4 pin connector through.
I used a hot glue gun to seal the holes, but any type of epoxy or thick glue should work.
I then drilled a hole in the tower to route the other end of the 4 pin connector through;

I used telephone wire to run through the tower, mostly because its very small and easy to run;
