[flash]

this is one that was requested by many of you - i wanted to give it a try, and an opportunity came up as a result of a mishap that prevented us from doing the job scheduled for the day - so, we made lemonade

the result was a very nice sounding "box" - the final result depends on the speaker you choose, but the box sounds good - very easy and inexpensive too

Just did the same thing yesterday. I regret not stopping to compare the left to the unmodded right though.
I went through 3 cans of foam, don't think I had as much expansion as Flash did - different brand of foam. Did realize one thing about my cubby sub though. I was going to put a speaker grill in the left carpet flap but I noticed that the flap up or down made almost no difference in the bass output. Finally dawned me that the bass was being ported up the inside of the wheel well and coming out the air vents by the window. So now I don't have to cut up my carpet flap and I will have a much cleaner, stock look.

joel - glad it worked out

dave - carpet flap? yeah - i was specific about the foam for a reason - the acoustic properties are specific to the brand and model of foam - i didn't want high density foam, as it would resonate low mid frequencies, so i chose the super expanding stuff - how was the bass being ported into the wheel well? there should have been foam all around the new vent tube - that tube is there to provide flow to the vents, which is necessary for defrosting, but there should be foam all around it to seal off the rest

I was referring to the 2 cubby flaps that cover them. I was just noting that I can leave the right cubby cover down and the bass rises inside the rear body where the sunroof actuator sits and comes out the vent holes with the hot air. I don't need to remove that flap and put a speaker grill in as I can hardly notice any sub degredation. It's only an 8" to fill in the bottom end. I also removed all the extra plastic and fibre board behind the rear speaker grills so the sound can escape a little better as I didn't want to cut extra holes below the existing grills.
Now for the weather.....

i'm thoroughly confused - the "cubby" areas have nothing to do with this, and there should be no passage of air from the rear speaker area to the rear of the car - if you did it like i showed, it completely encloses the rear speakers

did you do something different?

Herein lies the problem with non-face to face communication [img]style_emoticons/<#EMO_DIR#>/wink.gif[/img]
You are correct, the cubby has nothing to do with the speaker enclosure project. I was simply trying to note that while doing the project I had been elightened on the path of the air throught the door, up the dryer hose and out the slots at the back out the rear window. These slots, which I didn't really think about having function before (for the hot defrost air) also lead down to the cubby where my sub lies thus allowing sound from my sub to use as a path.
Clear as mud? Anyway all is wonderful and good!

ah - got it - yeah - sometimes it's hard to communicate here

yes, that vent on the door jam is to feed the hvac air through the side of the car back to the rear window - the tube inserted maintains that - the foam sprayed around it forms a sealed chamber, without losing the flow to the rear

so yes, the sub sound will find its way forward up those through those little vent holes into the passenger area, though i tend to think it might be muddy and resonant - i would put some dynamat on the sheet metal behind those vents to minimize that
