I'm building the system in my 2nd car, and the time has come to attack the sub-issue.
The car is an Acura Integra GSR Sedan, and its a second car, that I need to keep the utility of, so space is an issue, and I need to be able to fold down the rear seat, and use the pass-through.
I also want to keep the rear seat shut all the time, to keep what pressure I can behind the 8" bass/midbass/midrange I have in the hatshelf.
I'm a SQ guy, so a simple sealed box is my choice, but I don't like the sound of boxes in a sealed in a trunk.
I've built a bandpass before, but the lack of accuracy, and "boomyness" wouldn't give me what I want. So building a tall/skinny BP, tucked to one side of the trunk, ported through the hatshelf, really isnt an option - unless there is something new I dont know about BP boxes (which there is alot I dont know about cabinet design).
Putting a 12" (largest that will fit) in my hatshelf, and building a seald box down to the bottom of the trunk isnt an option, because I have alot of moving linkage lining the underside of the shelf.
So - I need educated/expereinced advice on how to get the most accurate bass I can into the cabin, because like I said, I just dont like the sound of a sealed box - in a sealed trunk.
Haven't decided on what sub-driver to use yet, but space is an issue, so Im looking at a 10". My 8's in my rear deck go down to 35hz and pretty smoothly down to 40hz, so I just need a little bottom end.
Question - will building a ported box -porting it through the shelf, and running the speaker out of phase do me any good?
Or is the simple sealed box in my sealed trunk still the best I can hope for with my needs?
Any and all help is much appreciated - I hope to start building something within the next few weeks.
