Well, I get to play with CNC's at work and some other fun stuff my boss gave me the ok to run some parts when the time comes. So, I am going to see if there is any interest in pre cut/drilled kit for fiero footwell sub boxes. I will offer a ported version good for 1 cf that will run a port under the dash and vent next to the blue dinger thing or a sealed box that will be good for .6 cf. The boxes will use polyfill or foam, I have not decided yet. In the ported versions the blue dinger will have to be removed to allow room for the port. I am also thinking about offering up a kit where the box will be tuned for a Fi q12 sub but the cost will sky rocket because of the cost of the sub. If I have everything planned out correctly the cost will be 55 shipped for CNC cut MDF, pre drilled MDF, all hardware to screw it together and double sided foam tape to seal the box together. I will be building 2 prototypes on firday. Sub sizes will be for 10's and 12's. I will not be taking any deposits what so ever as the start up cost is pretty low for me.
Heh, I am in the process of building one of these as well...
You get a lot more air space in the foot well than you do under the dash.
I actually thought up another ported version that will get me even more airspace, I just need to figure out if the design will be easy to tune. Im also trying to figure out how to get it installed without removing the dash..... So far the ported version I was talking about previously should be able to be removed from the car with ease. The ported box I though up tonight.....not so much. Im also trying to design the sealed box for a 10 to fit in the rear trunk so it can be removed incase your passenger does not like the amount of leg room.
Wondering if back the front works for RHD. Same parts glued opposite as just a thought. Not sure if the fiero foot wells are same left and right i know 75 corvettes certainly are not as the foot wells were extended when my folks did their conversion.
Ok, so apparently the CNC at work broke because someone was using it for a at home project, the boss is pissed and told us no more at home projects....So the box will now be of fiberglass....I plan on laying a few layers of tape over the carpet in the footwell and throwing fiberglass over it. I will then make a MDF "top" for the box and seal her up tight and fill it with a magical goop....this will create a plug for my fiberglass work.....The cost of material will be the same but shipping will go up a little. I am laying glass tomorrow after work.
Ok, so fiberglass, resin, MDF, dowel rods bla bla bla aint cheap. The kits WILL not be that cheap anymore, however with time involved, material and labor of making the plugs, molds ect...I will try to keep the cost below 100. I will also offer counter sunk kits for a few bones more. For the price you will get 1 complete sealed footwell box ready to go in made with 7 layers of glass. I am letting glass set up now and in a hour or 2 throw some more on, then let it set 24 hours and then remove it from the car. I still have to make a mold of the under side of the dash and a few other things, after my molds are complete I will then make a plug. After the plug is made its easy street from there, throw the glass and walk away. I will update with pictures in a hour or so.
ITS OUT! The mold is out Backside And this is in a completely different fiero, I put it in 2 different cars infact..... fits like a glove Please ignore the chunks of crap, I was glassing under a tree.
Even if you don't sell any I will be following this thread so keep up the progress please. I'm always interested in seeing what people do when it comes to sub boxes in a Fiero .
No work on the box today. Tomorrow will be a fun filled day with bondo....and more fiberglass.....then bondo......then primer.....then sanding.....then primer.....then wood.
Take a lint roller over it to smooth it out even more. Also, get a fan on the other side of the car pulling air out or have one behind you blowing air in. Each layer takes about 10 minutes to lay and the resin quickly fills the cab with all sorts of nasty crap you dont want to breath. If possible wear a resperatior. I want to see how yours turns out
I left the floor mats in place as you can see. I figured it will be a "true" fit if I did. I almost took them out but I figured what the heck. Its minimal space. It should be fine. Thanks for the air flow comment. I do not have a respirator anymore. I lost it about 4 moves ago. I used to have one from when I painted boats. Not anymore. But I'm working in my carport and it is open. I should be ok. I hope to lay some resin tonight. I will update you later. Problem is I have to drive it tomorrow. Do you think it will be ok to drive tomorrow, or should I wait until the weekend? I will be driving my truck then.
A club member built one of those style boxes a few years ago, used the foot well as the mold and laid the glass into the foot well over some sort of plastic. Once the back of the box was done I believe he used MDF on the face. He has since got out of Fiero's and offered it to me, sans sub. I just ordered a 12 inch 500w RMS / 1000w Peak sub to go in there. Should sound really good in the Fiero. Yes the passengers will have to sit with their legs crossed sideways in front of the seat. However with 2 kids now, the Fiero will mostly just be used for me to go running around town. We have another member with 8 subs in his Fiero yes Eight and 2000watts + of amps in the front compartment, and I don't want to be that nuts, but a nice single twelve will be great.

my two cents... I had thought of this a while back, but didnt want to fiddle with the fiberglass to make it fit snug, I was thinking in my own plans to stick with the basic MDF boards, and cut them in such a way that they would fit snug enough and then fasten it with some straps and/or screws.
My thought was to make it flush all the way across to the dead pedal/foot rest. and if the sub was to be mounted facing the passenger, I would then fab up a metal grate and set the mounting surface back a few inches so the sub would be protected (if the sub is too big for the footwell that there cant be some sort of foot rest for the left foot as well), if it was to be set on top instead, then all that extra hassle could be avoided.

That is exactly what i am doing. Putting in a JL Audio 12w6.

Actually with his separate mids and tweets and IIRC a Center channel was in the middle of the dash, it sounded really amazing. The pics in that thread were early on in the build more stuff was added later. He actually as the car up for sale now on Craigslist.

Well I made a discovery today. The supplied resin in the bondo kit isn't enough. Needless to say, I easily ran out and have to buy more tomorrow and hardener. :-(
