My alpine works. So it is b/c there is no power supply getting to the amp. And ya, lol. I read the instructions that said to use the volume controls on the modules. I've turned them up and down.

Here is my experience with the GMOS-09 I had the exact same problem and I could never figure it out. Remember Darcy? I took it in and they said that that one was the wrong one. I still dont know which is the right one, because I got so fed up with it I decided just to go with all new door speakers ran the wires got rid of the monsoon amp (added an aftermarket one) and was working on the sub until I got into my accident. The GMOS is not going to work unless you do something I havent tried yet, and I have tried everything I could think of to get that moonson amp working. I think Firehawk may have the right Harness though PM him.

I've never believed the volume settings in the module had anything to do with this problem, which is why I never mentioned them. I must aplogize Vince, I got side tracked and totally forgot about you

KTBoom2006, I'm not sure it'* worth giving up just yet. I'd still like to see you make the voltage measurement I mentioned and post that information. I'd like to see if we can't get this to work. This could ultimately help a number of members.

I think we are going to run a remote wire to the amp this evening

I just talked to Metra and the guy told me after checking things that he doesn't know what is wrong. He said it sounds like to him my amp is being told to turn on or there isn't any power going to the amp. So basically still no sound dang it!

Okay, define "checking things". Did you try what I suggested? This may be very helpful. Remember that not every "help desk" person will be helpful.

I pm'd you the complete wiring diagram for the Radio Circuit With Amplifier, but on another forum, since copyright material cannot be posted on here, even if it was purchased and distributed by an automotive electronics forum.

You mean this information ???

It'* the same between 2002 and 2003. Links (such as this) can be posted here. As for the info on the Alpine deck, I've already posted a link to their site.

Nope, totally different, and much more simple. If you want me to, I can PM it to you.\

Mine is 2001 specific, however, so it may not work in this case, but in general is something to look at.

Also, I would meter the amp turn on lead at the amp itself. If the radio'* on, and nothing at the amp, then obviously there'* a problem.

A simple 18 gauge wire will do the trick for testing. Fused, of course, with a 3-5 amp fuse should be more than plenty.

I'd be curious in seeing it. There are some minor differences in the '00 - '01 versus '02 and newer. I don't believe the change is relevant here since IIRC it'* only with the amp present signal. This becomes a factor when using the OEM HU.
