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

Fits me perfectly. I connected the amp and new speakers to my factory head unit which doesn't have a remote amp output. So I bought this to act as a long distance signal. I connected all the power wires directly to my amp and then connected the blue wire to the preamp speaker wire. Now my amp turns on when I turn on the radio and there is no longer a loud popping sound due to the delay. I would recommend it to anyone who doesn't have a remote control cable attached to their main unit.
