>>My main concern is actually how to avoid spaghetti in the rack. I know how to wire the cable I just don't know how to keep everything looking neat and tidy.Tie wraps, cable clamps, cable troughs(sp), etc.
>>It sounds like I would have to splice the 8-pole cable and put on 3 different Speakon ends to plug into the amps from what you are saying.
Yup.
>>Are there any pics posted anywhere that show the physical wiring of a triamp setup going into one 8-pole cable?
Not sure, I'm sure there is somewhere on the web.
>> Are there any type of junction boxes or Speakon patch bays that can be used?
Yes, follow the link below, you can find Middle Atlantic dealers around, I think Musicians Friend carries there products, Full compass etc.
