2004 and Bose 6 disc. Added PAC AOEM-GM24 to interface to 4 channel amp and new speakers. I read the little piece of paper that came with the adapter that said that there is no way for PAC to keep the rear speakers from playing when someone activates the rear seat audio controls. I thought, no problem, I'll just fade to the front and those in the back on the headphones would be fine. I like having a fade control on the head unit, so I hooked patchcords to all 4 outputs on the adapter and hooked them to the amp.
Wrong.
Everthing works fine with normal stereo listening, but last night I thought I'd turn on the rear seat audio to see how bad the issue was. The normal head unit output was on like two notches on the volume, the two knobs on the RSA control were all the way counterclockwise --- AND A NOISE ERUPTED FROM MY REAR SPEAKERS THAT WAS LOUD ENOUGH TO MAKE MY EARS RING FOR A COUPLE MINUTES AFTERWARD (I am not exagerating). It was audio signal, but distorted and boosted to the moon. Killing the power on the RSA stopped it, and (knock on wood) my brand new Alpines seem to be okay, but it certainly could have blown those speakers.
I guess it's mono output from the AOEM-GM24 and good-bye fader. I can't have someone hitting that by accident while I'm driving. Might scare me off the road and blow my speakers. (btw, I might have had the headphones plugged in, but I honestly can't remember. seems like I would have had to. I might experiment, but this time I'll have the amp levels all the way down.)
I welcome replies with work-arounds or similar experiences. I've only seen one other post where this was experienced, but they had the rear outs hooked to the sub amp, not a rear stereo channel like mine. I'm sorry, but PAC needs a better warning message.
