How to isolate speaker/panel rattles?

[super20g]

Is there a way to send a range of test tones to each speaker individually so you can isolate where rattles and/or distortion are coming from?

Or the best one can do is to use the fader to isolate a group of speakers at a time to test?

find the tone test on Spotify, this is what the ranger did when he came out to find a rattle in the door panel, turned out to be a door control module that need felt behind it.

I wouldn't think it'd be necessary to isolate the speakers to find the rattles. Install a test tone app to your phone and play via BT car audio. Once you nailed an excitation frequency, it's usually very obvious where the offending rattle is coming from.
