Does ANYONE know where I can find specs on the Alpine VR-12 sub. It's an older model, we are talking 3-4 years by now. I'm definetly in need of them. Let me know where I can potentially find either an owners manual or spec sheet!

Thanks

Alpine reccomends a 1.3 cube box with 2 9.5" long ports, , 2" in diameter. For a balanced system.

If you want to see all the stuff, , you need to make a user name and password on alpines web site in there tech section.
