first of al I have never built a box. But I just purchased 2 id max 12 v3 d4 and I need a box for them. I have heard alot about tuning, ports, volume etc. etc. I have a Mitsubishi Lnacer so there is not alot of room. But I want a box that is worthy of these subs. The box I have now is big but I'm not sure of the volume, tuning and all the other stuff. Please help me because I am lost and right now I just have those subs sitting around. Thanks for any help.
