LoL...I know for a fact I didn't hook it up. See, when I first completed the install, I couldn't figure out why the hell my amps would be working properly when I had the radio on, but when I switched sources to the CD drive or USB drive, the amps would turn off. Lo and behold, the radio antenna power lead =/= remote turn on for the CD7100. Duly noting this, I disconnected the ant turn on lead and spliced the remote turn on to the amp remote wire and wa-la, it works. I just crimped a butt splice to the end of the antenna turn on lead and left it alone. Radio works fine
