ive made a mdf floor with the subwoofer in the middle with the spare wheel well right underneath. how do i seal the false floor to the well. i was toying with the idea of making a box in the well but it would be too small so im wanting to use the whole wheel well space. as anyone got any ideas or pics? i need the sub in floor because the hole is cut and need the space of the boot thankyou

I used a lot of weather stripping foam, loaded it up with a crap load of sealant, then screwed it down to the floor in my friend's Del Sol

do you mean load it up with sealant inside the wheel well so its full or just on the sides

There's no way that you're going to seal that well enough for a subwoofer's pressure. If you need the full volume of the wheel well, my best suggestion is that you build a fiberglass speaker box using your wheel well as a mold. They are not hard to do. (make sure to use all fiberglass precautions, mask, gloves, and so on)

-Clean out the wheel well and trunk as best you can.
-Lay down alluminum foil inside your trunk and wheel well, taping down the edges, making sure nothing is exposed.
-Using a good quality resin (not the home depot crap, get it from a boating supply shop, it's cheaper and higher quality), lay down 6+ layers of matt going about 3"s past the lipof where your "false floor" (hopefully made of 5/8" or greater MDF) meets the contour of the trunk.
-Glass in the MDF to the fiberglass you laid already, making it one unit.
-after the resin has set, pull the whole thing out, trim the excess fiberglass leaving a lip of 1-2"s, pull the foil off of everything.
-Place strips of single sided foam tape on the bottom of the box, to keep vibrations down.
-place a strip of thin single sided foam around the edge of the box. screw the box down through the sheet metal using short self tapping screws (make sure not to drill into the fuel tank or anything under the trunk.

Voila, a custom sub box for your car. It can be as elaborate, or as simple as you want.Mine has a contoured carbon fiber top but is hidden 99% of the time with factory like carpet.

I have never managed to master fiberglass so I did the "stealth install" in my supra all in MDF and managed to make the box big enough by designing it as an octagon. Here are some pictures of that install to give you some ideas. I dont know if the supra spare hole is bigger than the celica, but I beleive I managed 1.25cu.ft. which worked well with the infinity 1242w I put in it. With the cover down it was impossible to tell there was anything installed back there.

I used it to make a seal all of the way around it, it's airtight.

Interesting setup there Facime but if I were to do this I would go with temperacerguy's route.

I agree with doing it out of fiberglass if you are comfortable working with it. At the time I did that I was rooming with a cabinet maker and so access to wood working tools and free materials made it a no brainer for me. The whole project took me less than a day to complete start to finish. The concept of the false floor was what I was trying to show the OP.

Free Air Subs !!! Or small footprint subs. I run a Pioneer 12" that only needs 1 cubic foot box. Takes up no space in my trunk.
Using the spare wheel area sucks when you blow a flat and have no wheel :)

I have a pair of those pioneers in my saturn sky. They REALLY suck for the wattage put out, and they have very little DB for even the size of the box. They are better than free air subs however... free air subs have very little resolution. and are not much better than putting a pair of 6x9"s back there

I have tripple A as well as another member on here. However I have this installed in my celica

"Saturn sky 12v pump and fix-a-flat sealant (http://cgi.ebay.com/ebaymotors/2009-Saturn-Sky-12V-Tire-Air-Pump-/200540186068)

The picture there is pretty crappy, but here's a description... the saturn sky/pontiac solstice don't have room for a spare tire, as such, GM gives this compact 12V pump (that runs off the cigarette lighter) with an incorporated can of fix-a-flat. you screw it onto the valve stem, plug in the 12V and flip the switch. It then pumps the contents of the sealant into the tire, then inflates the tire. The whole unit is about 10"x 4"x6"s, weighs less than 4 lbs, and is cheap. It came with a polystyrine holder that I hacked up and used for a mold to make a fiberglass holder that's incorporated into the false floor, but could easily be tucked away under a seat or strapped to the trunk somewhere. While it's true that fix-a-flats will destroy the lining of the tire, I am of the belief that performance tires should never be pluged and only replaced anyways.

what do you mean ????

Canadian Auto Association vs. American Auto Association.

You chaps use "The AA" because vehicular usage is all proper in the UK.

I enjoy having my full size spare, that is why I went with modified shallow subs in my doors. Sure Akon doesn't rattle storefront windows, but I have low end where I need it, inside my car.
