does anyone have any ideas of how to build a sub box around that damn hump the spare tire leaves in the trunk? I'm lookin at puttin in 2 10's, but all the pre-made boxes will have the box leaning on an angle because of the hump.

any suggestions welcome, except for fibreglass becuase i'm not rich...lol

i managed to fit a double box in there, its not custom or anything i just put it on an angle, ill take some pics and show you

the pic is on my page check it out

I cut the mounting bracket that the spare tire screws into off and screwed in some sheet mettle to cover the whole. you really cant make a sub box fit down there unless its fiberglass though, I use to have a tripple stack of amps down there but now ironictly enough I just put the spare back in there with no way to screw it down.

fiberglass is very cheap to do probably cheaper then making a wood box fit down there since all you have to do is fiberglass the bottum and make a flat fiberglass top peace with a hole in it to match the sub size (10" 12" etc.) and fiberglass looks way better, just takes more time to make (maily dry time and sanding time.)

i made a sub box out of fiberglass in the left corner for a kicker L5 8" i have some picks before i painted it. but it is finished and painted glossy black on the front and carpeted on the back. sorry about the quality took it wit my phone.

sorry didn't realize forum doesn't use html tags lol it gives quite a kick and only cost me about 40 bucks in parts plus 12 for paint/primer/clear coat

that's exactly how i want my subs ( but not that high cuz its only 2 10's) but i'd want one on either side. Nice job man, if only I could make a sub box with fiberglass....

it's not too difficult to make something like that i would say i am fairly new to fiberglass( this was my first big project) i would say if you do not wish to have it paint it the work part should not take more than 6 hours excluding drying time for the fiberglass this took about 1 month to make start to finish. you start by taping 2 layers of foil to the shape of the cavity, using masking tape (foil makes it easy to remove and protects well). the you buy some fiberglass mat with resin and apply 2 layers to a set point for the depth of the sub. allows to dry for about 6 hours then pull out mold from car. cut the edges to make it a nice even cut all around. use some wood scrap/sticks/rods and fiberglass those on both sides of box (woodside and fiberglass side) this will help hold up the wooden peice while you finish wrapping it. also it is advised that to squeege out excess resin from cloth for maximum hardness although i didn't bother with it.

^ Yup, I maid a fiberglass box for 2 10's on that side of the trunk. did the same thing for the mold, sept it took me a long time to get it done just because I put it off so long.



it now just sits in my garage because I got a single 12" rather then the 2 10's

looks good couldn't have take better pictures of production myself. those are some big subs audiobahn always oversizes everything how do they sound?

you know how with wooden sub boxes, there needs to be a certain amount of volume for air. Does it not matter for fiberglass enclosures?

not very good, the subs where good but the way the box was placed it maid a lot of vibration. maily because it was not well secured to the car, no place to really bult it down right. I replaced em with a 12" Eclipse Titanium duel coil sub, which is amazing.

yes volume matters in fiberglass boxes as well, but its harder to get very exact, mine was about 1.3 cubic feet but I dont know for shure, subs tend to sound much more boomy in fiberglass boxes

it does so i usually try to get as much volums as i can but since fiberglass molds into the space it is alot easy to meet or exceed the volume requirements. i think the12volt.com might be that site that calculates the space needed for which sub. but i'm not sure.

sould say the needed volume in the sub manual or on the subs manufactuers site in the specs

Hi, I was wondering if a fiberglass box could suport W6 making about 550Watts? I mean my MDF box right now has double wall to make it harder. Thanks

yeah you can just keep adding layers of fiberglass untill its stron enough.

when i did my system i had the hump in the middle so i just got a 1in sheet of plywood and took the carpet out of the trunk and made an outline of it and put it down as the new floor. it worked out very well.

I have 3 layer of fiberglass mat on it and i could stand on top of my box without it flexing at all. so fiberglass is pretty strong (except the cheap stuff they use for bodykits which say are 7 layers but are more like 1 or at most 2 lol) but ya for a sub to sound good it doesn't take that much glass to make it sealed and strong
