I have an old box from my Tahoe and looking to sell, but not sure the worth because everything was done as a package. They are two 12" JL Audio subs.

 

JL subs are worth anywhere from $50-$500, used, depending on what model they are... you need to take one outta the box and see what the back of it says for model #. Unless it says like w6 or w7 on the front of the cone...

 

any pictures of the setup?
