Here is my situation, my Vanagon camper is in need of a sub. But space is very limited, A friend of mine has an sub-enclosure in the rear seat cabinet, but this eats up a lot of storage. So I came up with this scheme of building an enclosure on one side of the cabinet that is not much use, incorporating the very walls of the cabinet as part of the enclosure. The the only problem is I have no idea on how to do this or even be possible. Can any of the sub-woofer experts help? Or are there any links that can explain construction techniques? Here is a pic of my situation:
The area where the speaker would be mounted, 8” most likely.
This is what the inside of the cabinet looks like, the space I want to use is 8” wide, 12” long at the floor and about 18” long at the top. It is about 20” deep. There is some dead space between the side and seat cabinet that could be used to channel airflow.
I am not much of an audio expert and don’t need anything earth shattering, just some bottom end. If this seems non-workable I figured my other options are:
A 6” bazooka, anything bigger won’t fit. Should I go amp or passive? Are these any good? Has the bonus of minimal work.
A free-air sub? These seem to be new tech, but do they actually work? Kicker seems to have some of these.
So what can you guys recommend?
Thanks much…………………….
