I just bought a single altas 15 to go in my 2 door ford expolrer and am planning on powering it with an MTX Thunder 421D. I need some advice on finding a box. I don't have the necessary skills/tools to build my own so i was considering buying a prefab box. How will this sound in a SubZone H-151 15" sealed enclosure (2.5cf)? I am more concerned about sound quality/accuracy than loudness. Are there any other boxes that might be a better fit. Will a custom box make a significant difference over a prefab boxes? Can you typically have a box built by a local shop? Any idea what something like that would cost?
