Just wanted to share my experience.

I blew my sub and passenger door speaker about the same time 2 months ago. I was so tired of having to put the sub to 0 and unbalance the sound away from the blown speaker so I looked for a solution, another solution than buying a new sub and speaker.

I first took off the sub and speaker and found simple ways to fix them both.

First of all, my subs cone was ripped from voice coil. The simple fix for that was to use epoxy glue and with a toothpick to put some glue between the cone and voice coil. Let it set about 30 minutes and make a smaller 2nd application.

For the speaker, I had about a 1 inch tear in the cone. I used the coffee filter method which consists of having some school glue (or in my case gorilla glue), mix 3 parts glue and 1 parts water, mix well. Then use a brush to apply a thin layer along and around the crack, on both sides of the cone. Let it dry out a bit, then cut a piece of coffee filter big enough to cover the crack and the area around and apply it to the still sticky crack, again, on both sides. If you used school glue, just cover the filter patch with the mixture and let it dry about 3 hours, if you used gorilla glue, you'll have to cook up a new batch because the old one is starting to set and is useless. Watch out with the gorilla glue to apply a very thin layer because it takes a lot of expansion and will affect the sound quality, but when it's applied in such a thin layer, it doesn't.

Here are some pictures of the set speakers:










After installing the speakers, they sound as good as new. And if they break again, then i'll replace.

 

 

It sure is!!! It was more of an experiment to see how long a redneck repair could last

 

points for ingenuity though
