I am replacing my 1LT's stock radio and found that there is an amp under the passenger floor board. Does anyone know what the pinouts are for the amps connectors? I'm having a heck of a time finding any info about the amp. I've looked through every thread I could find and no one mentions the amps wiring harnesses.

What's your plan? If you're going to replace the amp don't worry about the pinouts of the amp, it's the pinouts on the head you want. In ALL the stereos in the C6 (Bose & non-Bose) there are low-level outputs available at the radio harness. If you're going to add an amp tap in THERE and feed the signal to your amp.
Head over to the Audio/Electronics section. Stickied at the top is a C6 Audio FAQ and includes a couple of threads involving this topic, including a couple of how-to's that I wrote up.

First, great writeup, it's helped me to figure out what is going on under the dash.
I'm trying to do things in stages and I swapped the stock head unit with a new one and there is a noticeable hiss coming from the speakers even with the volume at zero. I suspect the crappy stock amp is the culprit and wanted to remove it to see if I'm correct.
Rewiring the speakers is the next step, but I was hoping there was an easier way to bypass the amp for troubleshooting.

How do you have the aftermarket head connected to the stock amp? Did you get a module of some sort (PAC, Peripheral, Metra) or did you splice in? If you spliced in, which wires on your aftermarket head did you use to splice in from?

Used the metra. It was actually one of the easiest installs I've ever done. I didn't even realize the 1LT had and amp and was none too happy when I heard the hiss.
I think it was one of your how tos that showed the space in the passenger foot well, so I was making room for my NAV and found the amp.

That diagram of the service manual. If you're a modder it's $100-ish very well spent. Any of the parts sellers here on the forum sell the set, I got mine from Fitchner. That actual pic may be from the digital version, which isn't publically available(or not supposed to be! )
OK so the Metra was a good way to do it. So what did you plug into the Metra? What I'm concerned about with the hiss is that you used the speaker level outputs of your new head instead of RCA/line-level outputs. That will definitley introduce hiss. One of those "start with the simple" kinda troubleshooting questions.

I have a kenwood DDX6019, it comes with a harness and I connected that to the metra. I was going to replace speakers and add an amp later, so the speaker level outputs are connected through the metra.
I could do it all now, but I wanted to do some speaker research first. I figured I could live with the stock speakers for a little while.

The speaker level outputs aren't the best to use. I strongly suggest instead of hooking up the Metra via the Kenwood's wiring harness to instead connect the RCA pre-amp outputs (From Crutchfield I see that model has 3 sets of outputs) to the Metra. The amp in the Kenwood combined with the stock amp is running away the most likely source of the noise.

You wouldn't happen to have an example of the RCA to speaker level adapter? Or do I need to cut some RCA cables? A link or pic would be outstanding.

Thanks for the help!
Before I do that.. which Metra module did you use? Do you remember the model number? That will give me both sides of the equation so I can best answer your question.

I was looking at your speaker install pics, what size speaker is that in your door? Edit: Nevermind I found your vert install post.
OK, what you need you can get at Radio Shack. Their web site is a mess for trying to find little parts like this, but what you need are 4 male RCA's that have individual positive and negative wires out the back. You would then tie those wires into the Metra's corresponding wires. The parts probably won't even run you $10. If you can't find them with wires you could just get RCA jacks and solder the Metra's wires to the posts on jacks.

Scroll down about 1/4 of the page and you'll see them. There are links to all the specs, installation sizes, etc.
Excellent. Thanks a ton. I'll head over to RadioShack at lunch. I've hesitated cutting anything in the hopes that I could find something to just plug in. I'm glad I waited.
this is the way to do it splice in some rca's to the metra harness and then plug that into the rca outs from the radio and tape off the leads coming from the radio
ARRRRGHHH.... This was supposed to be an easy head unit swap and it's turning into a nightmare.
So, I've changed the speaker outputs to the RCA and wired those to the Metra harness and the hissing is gone. Sounds great....
But now, when I shut everything down there is a loud POP from the speakers. I suspect it's the amp not powering down at the right time. Did I miss something or do I need to replace this amp now afterall?
