    Your basically looking for a "how to" fiberglass your spare tire well into an enclosure with an amp rack and trim panels so it all looks factory yeah? I have an 05 WRX sedan and am going to be starting one in it here in the very near futrue. I was thinking of making a mold of it so I could make another if I wanted. I'm not sure but I thought the 02 's trunk were alittle different than the 04 and 05's. Anybody know for sure? I've done alot of custom audio work using just about everything you could think of so depending on how crazy you want to get i'll probably have some pictures. Here's a couple of a 03 WRX wagon I did just alittle while ago. He wasn't concerned about space, just wanted it more for show. I had the N.O.S. bottles painted to match the exterior and had matching two tone gray / black vinyl. A person can also build it so everything is flat with removable trim panels that show off your equipment, you'll only lose a couple of inches of overall trunk floor height depending on what subs you have.

    First thing that you need to do is see how much air space is need. Then you need to know how much air space is in the spare tire well. I can tell you the spare tire well is about 1.25cft. I can also tell you that 2 12 will be a tight fit in the spare tire well.
    After you have done all the above you will need to make a frame out of MDF, line the trunk with wax paper and foil, and sterch some cloth and cover with resein. This sound easy but can a huge mess. here is a site that sell how to vids https://selectproducts.com/html/frame2/frames2.htm

    thanks for all the replies fellas. and i did some searching around and found some ideas for the enclosure. the spare tire well seems like the way to go for me even though i have 2 12s. i know how to do the fiberglassing as i am certified in paint and body and have done it proffessionally for a few years.

    i just hope the audiobahns that i have arent too much for the spare tire well.(i will check)

    and does anyone know if you can fiberglass over the mdf? so that it can be painted. i am not sure if this would work as i dont normally use fiberglass with wood or particle board.
    lol

    To paint MDF you don't have to glass it. You can seal and paint the MDF or use Bondo or the some like it and paint. But yes glass will stick to MDF. If you are running to 12" audiobahn subs I would say that you are going to need around 3cft of air space.

    With 2 12 the false floor will be hard to do. I have install 2 10 or 1 12 in false floors. A lot will depend on the air space needed and the size of the subs. If I was you I would built a custom box at fix the seat and do the amps and other gear in the false fool.

    A 12 in a .7 box will be boomy amd not very good sounding. The larger box will sound better and play a wide range. Check the freqs for each box, and power needs/ output.

    So is that 1.25cft. with the spare tire in place?

    Any sub really that works well in a sealed box. The fiberglass spare tire well works well cause you can conform the box to the odd well shape and use all that air that you would normally lose in a mdf enclosure. My 05 sedan has closer to 1.75 cubes when filled with packaging peanuts. Of course your going to lose some with the fiberglass and any braces you have in there. If it's too much air for the subs you want to use just put in an mdf divider that cuts the size of the well down before you fiberglass. I would either choose a JL Audio sub or a Diamond Audio one. Out of all the subs I've installed in my day those are by far the best. Both companies have different levels of subs and the key is to match them with the right powered amp. Both those companies entry level subwoofers are great. It really depends on how much bass your looking for. Two decent 10's in a well constructed box, with the proper power will outplay any set of seperates. Unless you want to be heard blocks down the road two 10's or one 12 will work great!

    thanks for the input.

    i have had every line of the JL subs (except the W7) and have loved them all except the
    W0s. they suck if you put any power to them, i have 2 audiobahn 12s now and they wont work with the spare tire enclosure and thats the way i want to go, and i think i am getting old because the 12s are getting to be too boomy for me. I want more of a punch now for rock music instead of the lower end for rap (not listening to it much anymore).

    is there anywhere online that still sells the w3s or w6s?
