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.

are you gonna be ok with mounting depth??

what about rattle? you are gonna have to dynamat the **** out of em...

i always like the sealed sound better...

what he said
and glassing isnt easy but i would say do by makeing a tub

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!

those are some nice drawings... you making them???

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

Mine doesn't..

talking about the front

While your tearing your doors apart anyway, why not make them point at ur ears?
