Alright so I roughly have around 4.5 to 6 cubic ft maybe. It's going to be inside of a 09 ford fusion. I know I can fit two twelves. But I really would love to fit in three 12 or two 15. Only issue is after building the box to be able to get the spare tire out still. I'm going to be pushing it and the box might be about 1 to 2 cubic on the small side of what is recommended. This is with displacement and ports calculated into the box. So I'm skeptical to see if it will work. It's very difficult to calculate this box by the way because it is just a bunch of angles. So any ways need help with this. I can fit 4 10/ and 3 12s for sure. Just my question is compared directly would 4 10s be louder and cable of hitting the same lows as two 15s? Or should I just stick with 12s?
Any helps appreciated thanks in advance
