Your vastly-more-accurate AF drivers* will probably do way too good a job reproducing that roller coaster of a frequency curve being sent out by the Bose amp, and you'll suddenly hear a bunch of peaks, valleys, and over-emphasized extremes of frequency. Keep in mind that this is completely different from the stock 1SS 1LE radio module, which does output a flat signal to the front speakers. We have the luxury of being able to tap that for amps that accept speaker-level inputs, but those with the 2SS Bose setup do not. I hope I'm wrong and that it sounds great. Let us know.

*I know how good they are because I have them too.

PS - I wish someone here had the equipment to accurately measure the stock speaker-level signals across the audible frequency range so we could reall see what GM gave us. I don't mean inferring the responose from SPL measurements in the cabin: that includes the driver's own response, which confuses the issue. 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.

I am not ignoring anything. My plan is my plan. I know exactly what you are saying, have known it, and am going to stick with this plan knowing full well it could suck. It could also not suck, or sound almost the same. I know this is the internet, and you think you are saving me from sticking my hand in a garbage disposal, but I assure you that this isn't a big deal.

My stereo sucks now, I estimate a 20% chance it is worse with the AFs in the door, and even if it is, I will just be one summer. I am coming up on my third summer living with terrible factory sound, so I think I can handle it. I am not painting over a Monet painting here, I am taking the art that a dog made on a pee pad and throwing it in the trash, then putting out a new pee pad for the next art installation.

In terms of the current Bose woofers in the doors - I would bet money that they perform well on paper. They have extended low frequency because of the noise cancellation - which generally runs well below 100 Hz. I bet they go down to 30 Hz or lower to cancel the exhaust 2nd and 4th order drones. I'll save them if anyone wants to run them through an analyzer.
