Who can post measurements for a sub enclosure to take the place of the spare tire in the rear for an 86 951.. (they are probably all the same.)

I will be building a box with 3/4" MDF for a 12" subwoofer. The sub will fire up toward the hatch out of the large space after removing the collapsable spare.

The sub I've got calls for .97 cu. ft. of airspace.

anyone done this? I dont see many posts of this nature on here. (yes I love listening to my motor rev and turbo spool, but love music almost as much.. and the 4 speaker design in my 951 is killing me. i've got to improve on it.

I don't have the dimensions but I don't think that you can get anything larger than .66 cubic feet of volume in there. Seems small with all those peculiar angles. I may be wrong but .97 cf seems too large to fit in there. Ever think of using the cubby holes on each side. You can build relatively simple boxes that will slip in and house 8's (Kicker Solobarics only require .33? cf.)...Good Luck

I have a much better idea for you. Let me know if you want detail. I wont bother posting them if you don't want them. I have built 3 different styles of sub enclosures for these cars. I have tested them with db meters, and multi, isolated, frequency cds. All of them were sealed isobaric subwoofer enclosures. I tried the spare tire enclosure, and it worked well as fare as sound goes. I have many requirements when I build a system in a car. The install I developed that I have found that works the best is to use the large side pockets in the fender wells. This allows you to keep all of your trunk space, and your spare tire. Also if you research sub frequencies you will find that the shape of the wells is perfect for subs. I make all of my enclosures out of fiberglass with mdf tops. This makes them much lighter and lets them conform to the shape of the car. With fiberglass you can also make the removable. Even if you don't use the wheel wells I suggest you use fiberglass. Just let me know if you want details.

I'd love to hear some details. How much would you make some for?

i want to see them too, im interested, i was in a 944 with a sub and it sounded great, and it was a ****ty setup

Eurospeed951,

Yes, actually, I am very interested in your design and product. You can email me the details, or since it seems others here are interested as well, post them here in the thread. The installer I talked to did indicate that it would be very dificult to make all MDF enclosures for the side wells, and fiberglass would be required. I would also prefer fiberglass for the weight differences as you indicated. My concern though, is that I already have a very nice IMO Polk EX 12" subwoofer that did sound incredible in my previous car. Two 8" solobarics is more money than I wanted to spend on just the subs alone before the cost of an enclosure. I would possibly on do a single enclosure setup. (passenger side of course). But, if you can do your enclosure with a round sub, then let me know that too, as it would save me some money there. One thing I worried about is that I noticed one day while cleaning the car, that my passenger side wheel well area was wet and some rags I had in there were completely soaked. I am not sure if this is normal and these areas are not sealed, or what. But if I put stereo equipment there, I would be worried about moisture.

thanks for the info eurospeed,

I was at the junk yard diging through the trash as usual when I stumbled upon some nice fiberglass enclosures. They are conformed to the shape of the back seat foot space behind the front seats. They fit perfectly and face upward at about 45deg. of course they restrict seat movement abit but I'm 6foot and still have room to adjust past were I usually set the seat. They have 8inch holes cut in them and I'm not sure as to the cf. I'm guessing ~1 or less. Pics to come if anyone is really interested.

I too am toying with putting my 8-inch subs in the cubbies. Right now I have two Nakamichi 8's in a box that uses entirely too much trunk space. I want to do the fiberglass in the cubbies. But, I have very little experience in this area. So, I am very interested in details. I am also receptive to buying the fiberglass and assembling the enclosure with my own MDF.

One of the other places that I recently thought about putting subs was the back seats. I recently stripped the interior and installed Dynamat Extreme to cut down on noise(noticeable improvement BTW). I removed the back seats and noticed that the seat wells could be customized with a single piece of wood and two conforming fiberglass enclosures. Cover the fiberboard with carpeting and it might make for a stock appearance. Of course you lose the use of the back seats and the car is no longer orignal. But, I haven't really ever used the back seats. And the rear seats can be easily reinstalled.

Eurospeed951, I'm also interested in hearing more details. Also where is everyone mnounting amps at? I have 2 amps to mount but not sure where to put them. I still want to keep room for the sunroof in the back so I was thinking of doing a false floor in the back with a couple of cooling fans. Has anyone ever done this? <img src="confused.gif" border="0">

Scott(aka slevy951) builds custom enclosures for 8's in the either side cubby hole. you might want to contact him for more ideas too.

you can view his enclosures <a href="http://members.rennlist.com/slevy6/subwoofer-1.htm" target="_blank">here</a>

Ok, my current setup is:
Sony CDX-m610 CD head unit
2 Memphis Audio 5 1/4 (in custom door panels
where stock speakers were)
2 Memphis Audio 6x9
2 sony xplod 12"subs (there is one sub and one 6x9 in a custom dual chambered enclosure in each fender well
1 sony 2 channel amp
1 Kenwood 4 channel amp(sorry, can't remember specs of amps, but both are in the spare tire well)

I never took any pictures of this setup, because I had not had time to finish the carpet around the 6x9's and subs.(didn't want you all to see something less then perfect )
The box in the spare tire well is much easier to make than the ones in the fender wells. This is because it is very hard to cut the wood pices at the correct angles.
THE SPARE TIRE BOX-
-clean the area very well
-use silicone caulking to close and seal any drain holes
-Cover the entire well with aluminum foil. This will keep the fiberglass from sticking to the car
-make a fiberglass mold of the well including a three inch lip around the top. If you have never used fiberglass before it is very simple. Basically you just lay down the fiberglass sheets, mix your resin and hardener, and saturate the sheets. Keep doing this till you have made a complete mold of the well. Let it dry over night.
-once it is hard remove the mold from the car
-build up the thickness of the box by adding more and more layers of fiberglass to the inside of the box. Do this till it is a 1/4" to 1/2" thick.
-once it is dry spray the inside of the box with primer. This will seal it and make a better finish.
-once it is dry measure and cut a piece of MDF or particle board to fit the top of the box. Don't worry about it sitting flush with the fiber glass, just make sure it sits flush in the car. Don't forget to cut the holes for the subs.
-spray the entire well and bottom of box with 2 layers of rubberized undercoating. This works just as good as dynomatt, but costs about a buck a can. IT IS VERY IMPORTANT TO LET THIS DRY COMPLETELY!
-Surround the top lip of the box with foam strips. I used the stuff to seal a truck top to the bed. It is sticky on one side.
-coat the foam and upper lip with Liquid Nails caulk
-place the MDF top on the box and screw it together
Drill a small hole on the bottom of the box and run your wires to the proper length
-use silicone caulk to seal the wire hole up
-place the box in the well
-install your subs and your ready to go!
You now have a badass box that can be removed easily at the track!
LET ME KNOW IF YOU HAVE ANY OTHER QUESTIONS!

heres the setup im going to ATTEMPT to make....

im going to take out the back seat...im going ot make 2 boxes...the lower box is going to hide my bottles.....then im going to set a box on top of that and try to put 3 12" vegas in there....right now i have 2 in a crummy box that i whipped up in about 2 hours....and they hit hard too....i figure i can spread it out more (air volume) and have 2 facing the back and one toward the front.... or get all 3 toward the back....havent decided yet....

*eurospeed951*

hey cowboy, I bet you $20 it would sound better if you faced your subs the other way!

ThE sPaCeCoWbOy

which way? what sub(s)?

im just going by what my friends tell me....i dont know jack about stereo equipment....i was told to face them paralle to the window in the back so thats what i did...

thanks,
