A:Answer 1.8 CU FT for vented box (sealed is less)
I highly recommend the Q bomb boxes.
Very well-made and sound great.
Also fond of the truck bed liner coating, but it’s secondary because it’s all about the sound!! Just be careful to not get a cheap knock-off, if purchasing from Amazon.
FYI: I recommend contacting the manufacture for these types of questions.
Alpine is on the West Coast but easy to get a hold of
