I just built a custom speaker box for 4 10 inch subs for my 99 cougar. The layout inside the box consists of 4 squares individually sealed. I only have two subs in it right now, and im waiting to cut out the holes for the other two when i get them.
The prefab box i had originally, hit really hard. The new one doesnt sound so great, actually sounds like crap, But looks awesome. I only enlarged the size of the box by a couple of inches per speaker not thinking it would be a big difference. I was wrong! The only options i can think of are: Putting something inside the box to cut down on air space for each speaker, or tearing the box down trying to salvage as much MDF as possible and building a new one that doesnt look as good. What can i do?
