I have a 1987 chevrolet celebrity. In the trunk there is the spare tire which i would like to take out, and put in my kicker comp VR 12. CD15 i believe is the model #, it's the older one. Can i just seal a pice of MDF over top of it and mount the sub in it? What do i have to do to complete this install? Should i sound deaden the wheel area? i'm lost but want to do it.
Thanks a lot
TJ

is there going to be enough airspace to meet the requirments of the sub. alos make sure its air tight, probably would sound horrible. sounds like a kewl idea but im sure its gonna be quite a task. plus ive never heard a sub that has half of the enclosure made out of metal might affect the sound. id definilty put something in the whole before ya seal it tho. maybe something like that do-it-yourself bed liners for trucks that ya spread around. probably would seal the inside of the whole plus my also deaden the noise. just my imput tho. id wait for the experts to come to the rescue

i dont think that it would sound horrible. I'm sure the air space is fine, it's not just a circle, there a little more to it b\c of where the jack goes. I'm sure it's not more than the recomended 2.2 cu ft for the sub, or less then the 1.8 cu ft. i have extra dynamat would that work?
Thanks

Dang, I posted some info earlier and for some reason, it did not add to this link...

In short, I think you will be fine if you know the cf internal space of the tire well and what sub maker recommends. If you are within +/- 15% of center target... that's fine.

Also, spray coat the tire well to seal it against air and water leaks. Use plywood (Marine)... as is better than MDF. MDF will fall apart in high moisture applicatations. A few coats of polyurethane or epoxy based paint will seal the plywood wood baffle panel just fine.

Also plan on using ~1.0-1.5 pounds of poly-fill to dampen any metal resonances that you might otherwise get w/o same. D-mat opr similar is fine... but do use something to dampen the metal resonances.

Finally, sealing the speaker baffle panel tightly is key. Avoid airleaks by using adequate amounts of RTV silicone sealer. Any gaps will be filled buy adequate amounts of RTV. Just allow the RTV to cure over night, before instaling the sub. You can put a 50 pound bag of sand...whatever, to get a tight seal.

Good luck and keep us posted on your outcome OK? I think it will work out fine if you stay within the internal cf specs of the sub.
