So i was watching a video of Steve meade from youtube using a
RM04 WIreless remote box
it a basic box 4 Wireless channel r, 4 output(+12,-) , 1 input to power the entire wireless unit

each channel have a +12volt and negative output wire

I was wondering how would i hook this up so that i can control an amp on 1 of the RM04 channel's

Remote on the amp only need a 12volt where would i put the negative? i try to do a mock up with a power supply it just short out and shut down my power supply(computer power supply box)


someone told me to run it to a relay how would i do that? anyone can draw me a drawing how this is done?
