Review on Enhance Your Audio System with the PAC TR-4 Remote Turn-on Module by Randy Brimmer

It states that the green wire should be connected to the speaker low voltage wire. I was hoping this would work to allow remote power on wire from the aftermarket Pioneer Head Service. Device for switching on several audio components. I connected the amplifiers (2), an electronic crossover and a 12V power supply with a digital voltage display to the blue wire and everything worked (so far so good). I never knew that the remote output cable was really only meant to be used for a remote audio computer. So this is new to me, glad I found it. I built a relay but found it a bit wobbly and could be a source of noise in the system.
