Could you flush mount them - letting them protrude say about 1/2 inch toward the seat? Use some MDF to space and seal? There is a little room to spare.
How much room would you need give the magnet a 1/8" clearance from the rear panel?
Could you cut some 5/8" MDF and mount to both sides securing the MDF to the top and bottom panels - thus making a airtight box? Might be a bit tight and you might need some RTV to seal the seams. then you could dampen the entire area with insulation.
Install and test - might possibly need a port - but it could thump...
Brian,
Essentially I took 2 inches of mdf (glue two 1" mdfs together) and sanded them to fit correctly and flush against the metal as well as the speakers + gave them a 5.5 in cutout hole for the speakers (you have to make the brackets into a wedge shape similar to the vent bracket shape). Then I created 3 holes in the outer rim of the bracket so that the bracket could be secured using the stock bolt and nuts. After securing the bracket it was pretty tight, and using some auto RTV on the edges would probably make seal it fairly well.
I did all of that assuming I would mount them with the cone protruding toward the seat, but after it was all done, I was still having issues with the magnet hitting the metal of the car (possibly due to my poor craftsmanship
).If you are able to get the magnet to clear all the metal, you still have to cut the carpet. When I lined it all up to see how I would have to cut the carpet, I found that about an inch of the speaker was behind a section of the carpet which was molded to curve toward the door
. I'm sure there is a way to get around this issue but I didn't explore it too much (i really hate carpet cutting, especially when things don't fit!!)
Another method I tried was to make a ~ 3/4 mdf bracket and attach the speaker to it, and attach the bracket with the speakers onto the stock location with the cone facing the trunk. The magnet will be facing the seats but will protrude quite a bit (somewhere around 2 inches and will require some carpet cutting). It would not look too pretty considering the stock hole in the carpet would be obvious along with a big chunk of magnet. You have to use 3/4 and cant use a small 1/4 due to the distance the speaker's cone and surround travel (a lot!).
And you are right about the port. I'm sure they would sound great in an enclosed system, but a ported one would make these things bump!!!
Like I said before, im a novice at this fabrication stuff, so im betting someone like yourself could figure out a great way to get these woofers to work. I probably wont spend too much more time on this specific project (mostly because i'm pretty busy this month) but ill keep ideas rolling in my head. I also appreciate any input (such as the input you have given)! If you have a knack for a challenge, you might consider investing in 1 of these speakers for 55 bucks and giving it a shot.
