Enclosure question for Alpine Type R
Ok guys so I'm planning to finally put some bass on my car, I know a bit of the electrical thing of car audio but I don't know anything about enclosures, so I want a sealed box for a type R 12", in the specs it says that the maximum volume would be 1 cu. ft. I don't plan on making a custom box so if I buy a enclosure at sonicelectronix it says thats a 1.0 cu. ft. So to that 1 cu. ft. I need to subtract the displacement of the sub right. The displacement of the sub would be like 0.10 cu. ft so that gets me a 0.90 cu. ft. box right?
Also when it says on the sub manual the gross volume of the box does it mean the box without the sub right? and when it says the net volume it would mean the box with the sub right?
Maybe they sound like dumb questions i don't know anything about it here in PR everyone put the some in tube like enclousures and nobody cares about the volume or space they are giving the subs like this:
