Daisy Chain 2 cabs in KPA

Hey Guys....I have 2 4x12 Trace Elliot guitar cabs. Can I daisy Chain them so I can use 2 cabs with the 1 cab output on my KPA?? If so.... What is the best way to do it?? As I have never Daisy chained cabs before in my life. Just want to make sure I'm doing it the right way. I've attached a pic of the back of the cab so you can see if it is doable or not.

Also... I read elsewhere on the forum that people have side you can use a palmer cab merger (http://www.palmer-germany.com/…-Cabinet-Merger-PCABM.htm).
I don't have that.... but I do have a Jet City Amp Switcher (http://www.jetcityamplification.com/#!pedalsboxestools/c5o3) You'll find it at the bottom of that page. However it isn't passive and runs off a 9v battery or power supply.

Any quick help would be appreciated here. I have band prac tonight with the KPA for the first time and would love to run it with 2 cabs!!

The power Kemper has a single speaker out which takes 8 or 16 ohms only. Not 4 ohms.

So how do I do the lead setup if I do a daisy chain method?? And will the Amp switcher box work like a Y cable??

Thanks for your reply Arie!!! Much Appreciated. So you would advise to stay clear of a speaker grade Y Cable??

you can buy 3 x mono jack input and connect them like in the picture (connect green connections all together and connect reed connections all together) and buy three speaker cables and small box for splitter:) it will cost you 5$ Or buy a palmer PCABM.

Thanks for this info Damian.... although I am pretty much useless when it comes to building/soldering/creating anything like this. I am destined to fork out more money and just buy the palmer box instead of being able to make one on the cheap. I look at your diagram and I can't work anything out lol. Thanks for your input though
