I bought a car a while ago that had a subwoofer set up installed with a JL Audio 8W3v3-4. It's an 8 inch and has great sound. I was getting a strong burning smell from it though. I have very little knowledge of the specifics of how this works. I was having some work done at car toys and asked them to look at it. They told me the amp was cranking way too much power into it and they said the speaker was blown. I now have a whole new system in my car and I've sold the rest of the old equipment except for the speaker.
What I don't know is if this speaker is still usable. Is it actually blown? There is no visible damage to it. If it is blown or unusable, is it repairable thus worth selling? Or should I just dispose of it and if so, what's the best way of doing so?
I'd really appreciate any advice on this. I'm going to include a couple photos just in case it might help.
