Well, I need to know what kind of tools I will need to build a simple sub. It's going to be a box, and I want it to have a nice finish. Really, all I need is a tool to make a ROUND hole. I am going to learn how to mount the drivers layer. I will be asking more on the BB when I have the right tools. I won't start unless Im sure I know what I'm doing I was thinking of using a Car audio driver. (Sub) Will this work? For now, I will be using a sony minisystem as the amp. (If it keeps shutting off, I will buy something else) And advice would be great!
