How do I run an extension cab with my combo or hook up 2 speaker cabs to my head?

This is an easy procedure.  First thing to do is get a quality Y Cable like the ones offered by Procables N Sound.  These cables are available in series or parallel wiring.  Always match the ohm rating of the extension cab to the ohm rating of your combo speaker.  The same goes for running 2 cabs.

Here's an example for parallel (the most common) connection:

1.) Disconnect your 8 ohm combo speaker form the back of the amp chassis and plug it into the Y cable.

2.) Plug the extension cab into the Y cable.  You now have two 8 ohm loads in parallel to make a 4 ohm load.

3.) Plug the Y cable into the 4 ohm speaker out on the rear of your amp.

Series connection is the same except that two 8 ohm loads make a 16 ohm load.  Not all Z amps have 16 ohm speaker outs so be sure to check your specific amp.
