Sound system upgrade

[_S7V7N_]

You going to purchase a prefabricated box ? You may save more money just getting a custom box built if you know anybody with the knowledge and skill to build one. Unless you have the tools yourself. I'm pretty sure if you posted the specs of your speakers, somebody could put together some measurements and port lengths , as a matter of fact a simple google search can send you in the right direction on what to look for as far as calculating what size box you need. That way if you're gonna buy a prefabed box you'll know what kind of sound to expect out of it.

Good luck with finding a new one.
