Nice Pics. Dont forget to tell everyone how well these amps perform on sub duty lol. These amplifiers are specifically made for each region and are not multi voltage.
You would have to go inside the amplifier and rewire the primaries and secondaries in series as far as I know, and this is not a job for dumb heads like me.
In Canada and the USA we can simply install a 230 vac line in our electrical panels and run 220 to 240 volt equipment with it. This is done simply by placing the double breaker 230 volt between the supply rails on the electrical panel and then running wire from this to an outlet. Myself I made a few small holes near the walls in my listening room and ran extra lines so I can have dedicated power lines for all my amplifiers. I do not know if you can do the reverse in 230 volt regions, by installing 120 volt lines in your panel.
Here is what I am powering up with the corner loaded amplifiers. lol

All the pro amps are for powering subwoofers.
A Good amplifier requires a adequate power supply, It does not matter what the amplifier is capable of if the power supply will not provide the power required. Most amplifiers have under rated power supplies. It is up to you to make sure you get the ones that are least under rated if at all.
