Hi everyone, i'm new to the forum, basically i bought a sub a few years ago, and i want to install it now into my car, the problem i have is i do not have any information at all about the sub, other than it was called "the rock" and it looks like the pictures attached, can anyone please give me any information about it, or at least point me in the right direction, of maybe who made it (it's a 12" sub)

thanks in advance
