Yes, and not only that, don't forget to hook up power for your antenna. I was getting crappy reception and couldn't figure out why, as usually the blue lead wire just runs the amp signal turn on, but with the antennas in the windows on the Armadas they need power to operate. So once I hooked up my antenna power, wow, it works!
Not trying to necro a post but I just installed an aftermarket radio in my 05 and got horrible reception. I hooked the power amp wires together hoping it would do the job and I still have bad reception, does the one from the "car side" of the harness need to go the 12 acc maybe instead of the one labelled power antenna on the radio side?
