Default 8'* in doors

Okay so I jumped into this without thinking about it very much.

Essentially what I am doing is putting 8" subs behind "almost" stock front doors. By almost I mean I already cut out around the component speaker holes to make a kidney-shaped opening and removed some material from the backing panel. New grilles will be fabricated.

My problem is this... I have narrowed the install down to two mounting options that will require similar amounts of work and I can't decide which route to go. I can fiberglass a .3cu.ft. tub that fits into the door cavity and somehow mount that to a baffle. Or, I can go about sealing the door off and running the driver IB. My 8'* are good for either.

Forcing my 5.25 components to play serious midbass is pointless, so I want the 8'* low-passed somewhere around 120Hz. I am hoping to run without any trunk bass. Obviously this is just an SQ experiment. I can always add a sub later... hehe.

Given my 1a.m. explanation, what arrangement do you think will work best - .3cu.ft. sealed or IB? Has anyone put 8'* in B-ville doors before? It seems like the perfect amount of space... Any guidance appreciated.

Find a way to make a box or something, keeping the area around the driver firm. If you could have it so there'* something between the outside of that panel, and pushes against the metal, it would actually hold the driver in place.

Mounting depth is sooooo not a problem. I am leaning towards the fiberglass tub as well... maybe backing the tub with thick foam will provide a pressure fit against the door? I am still trying to work out how to mount an MDF baffle to my door opening and have it be secure. I've got 5 gallons of damping at my disposal, so vibration shouldn't be a big problem.

Here is my idea so far... This is basically what the door looks like without the cover.


And this is how I think the baffle will work with the door. It is built out some where the woofer sits, and I can take it out a total of 3 inches if I need to. I really don't see .3cu.ft. being that hard to fit in, but then again things rarely are as they seem...


Any more ideas? Man, after I deaden everything and build these pods in, my doors are going to shut like a vault from all the weight!

Yeah I sketched it up real quick sitting out in my car, scanned it and did a quick coloring in Photoshop.
