Very good info, thanks! I'll definitely be using your thread when I get to that project!

I mean measuring the electrical frequency response at the signal wires. We need that for each variant of the Camaro's sound systems, and each pair of speakers to which they send signals. I'm an electrical moron and have no equipment, so I can't do it.

Yes. I had this exact info for the last car I upgraded, working with an EE who had a nice bench of test equipment.
We used an audio test CD with frequency sweeps at normalized volume. Set the car for medium to high "system" volume and then measure the electrical outputs at the various speaker feeds to get readings for the EQ and relative volumes.
To be honest, I thought the newer integrated gadgets had some kind of calibration mode which did this automatically.

So what ever happened with this? I think my passenger door speaker may be blown has the most annoying rattle with any base i plan to open things up and take a look and if I can swap it out with something. If not fix the issue that would be great

I bought a door kit from resonix, and all the speakers, adapters and harnesses. It is all still sitting in a pile in the garage. Hopefully a winter project! By the way, I did find out that the GS25 will mount in all three dash locations. That is all the progress I made though.

I have a video series detailing the Resonix product installation.

For those looking to understand how to tune a DSP to get your sound system dialed in, i've found this YouTube channel (not mine) to be the most comprehensive resource for how to use REW to fully analyze and tune the system.

Thank you by the way - I have been watching yours and the one from Resonix and taking notes. My biggest complaint on my factory system is the buzzy passenger door. I SWEAR I am going ot do it for spring!

Thanks! I'm able to play down to 40Hz in my doors with zero buzzing and enough output to sound like a small sub. All of the materials I use are necessary, not just deadening.

Another view of the factory EQ on the 1SS Non-Bose radio. I have access to a LT1 with Bose and will do similar measurements on that system soon.

Time for dumb questions:

1. In that graph, is the purple line for the left channel and the blue or cyan line is for the right? If so, are these front channels or rear? I thought the front channel outputs from the radio module were flat, but these are not flat!
2. If these are left and right channels, any idea why the levels are not equal across most of it?
