How to hardwire from the back?

Please use 12v dc cable to connect to 12v power supply.

Do they make one for a 3 pair speakers

Dear consumer, our product can only connect 2 pairs of speakers.

Is the power supply only by the device's front? Or, is possible too, to put the power supply through the wall?

If you mean hardwire it apparently you can but there is no instructions on how to do it. Mine came with what looked like two power connections on the inside and when I hook one of them up it fried the whole thing.

Great Unit

4 stars as the unit makes you utilize very small wire to hold into the plate. Had to downsize with wire nuts. Works great besides that.
