You may have damaged the speaker if it all got pushed together too hard, but if the speaker wires shorted on something, it's more likely it blew the amp in the decoder.

In your initial installation, your remark that the sound was very low indicates a problem. Normally, part of the installation process is to tweak the CVs to reduce the volume, as most decoders come from the factory set uncomfortably high.
I would check the speaker wiring, in particular. It may be that the connection was marginal to begin with and came off completely when you squeezed it into the shell.

It was a tight fit. Some wires were pinched. It ran hurkey-jurkey. I think I may have had a short somewhere.
Could I have blown the speaker? It looks fine. How can I run a test on it?
Sounds like you definitely disconnected/shorted something when the shell was installed. Any "funny" running characteristics other than no sound? Where does the speaker fit, and how does it look? Are any wires pinched?

Disconnected or broken speaker wires?Sounds turned off with F8?Speaker failure?
Is this a light board decoder or shrink wrapped decoder? Obvious something is amiss when the shell is installed.
Any exposed wries, splices? Are all connections soldered if a light board decoder? Check the bottom of the light board decoder as most parts are exposed.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
I just complete my first installation of a Tsunami sound decoder in a Bachmann GP7. I followed the Soundtraxx directions that I found on line and every thing worked fine when I tested it. Ran real nice, bell and horn sounds were good and engine sound was ok but very low. head and back lights worked fine.
However, when I re-assembled the body and tried to run it, at first I heard a slight clicking sound. When I pressed the horn, the head light would go on for a second then go off. It had no sound and the lights did not work.
I removed the body shell and tested it again. Now it runs ok and the lights work again. However, it has no sound. No horn, bell or engine sounds.
I've check all the wire connections and they all appear in good condition.
I'd appreciate any help.
Thanks
