they make one that big? i have a dremel but i'm not sure what youre talking about it would be awesome if i could just buy the materials to keep cost down

 

yeah its a arm thing, i think the center screws in and the arm swings around. kinda is good for me because i have the solo barics. square subs FTW

 

wow man that looks unreal!! nice work!

 

what is the volume of the enclosure?

 

i was just wondering what is the cost just for the materials for this? and how much time does it take?

 

lowes has the stuff. a pint of resin is about $13. a 3x3 mat of fiber glass is about $3. it takes serveral layers. your looking at around 75 - 100 for a good box. then you gotta buy some wood, dowels, and glue.

 

looks nice man. my favorite thing a bout it is the cap placement..great idea. cant wait to see how it comes out

 

lol **** thats hella nice, wish i could do something like that

 

When making your circles you should do the circle of yours subs, then ones you have done that to be safe add another 2 inchs all around the circle.
the cost so far for this box paint, wood, fiberglass costed around $150
its been a week and still not done, mainly cause i work 12- 18 hour days

thanks for all the comments

 

and how is that going to fit in your trunk?

 

good progress

 

yeah lets get some trunk pics.

 

Okay tomorrow if it ever stops raining i will put it in my trunk, basicly putting it in all i have to do is put it in side ways and KaBam its in.

 

if you want to go threw with it its really easy to remove the back seats and supplys a bit of extra room to slide it in

 

Its not going to slide in becasue of the corners he put on it. I honestly dont see how he will fit that in through the trunk. But I hope he knows more than i do

 

on the 1st page there is a pic of it in the trunk, but i just put some more bondo on it so i will get pics when its dry

 

yeah but that was before all the fiberglassing and all. I see you must be going in from the trunk because of the way the platform is built. that would make it to where it cant go in from the back seat. But it looks to big to be able to go in the trunk is what im saying

 

you can also use screen or chicken wire to form a mold ... or even cardboard and duct-tape over the card board then rip the card board out after ... Duct-tape is one of the few things fiberglass will not stick too.

i made the fenders, saddlebags (covered in leather) and tank on this out of fiberglass

 

UPDATE...

Everyone wanted to see how to put it in the trunk and how it looks in there, well here you go.

Goign in


And in.

 

looks good, im going to start mine soon. 1 question though.

subs need a specific airspace for maximum sound quality, how do you know how big your enclosure is going to be? i know you can fill it with water and then measure it that way. but how do you know before you build it?

 

This is looking really bad ass man, good job, keep it coming with the how to, Id really love to try this soon as a summer project

 

Basicly all i did was get on the internet, got what the air space that was needed for these subs, then did alot of math lol

 

-just a suggestion for computing the sub box actual volume( in case u dont know). make a 1 ft cubed box out of card board or take a already made box and make it into 1ft cubed space. fill your fg box all the way with foam peanuts or similar like bean bag chair material. then dump all of it into the premade box 1cubic ft at a time and you will know the internal volume. if you need to decrease the volume you can add mdf cubes or pieces inside and if you need to add volume polyfill works great.

-all in all it looks good but I def would have went with a stretchier material and pulled everything tight. also you don't need a thick cloth for the first wrapping. you just need a base to lay on the real reinforcement that comes with layers of fg mat. CA glue and staples are your best friend and will help make a project like this look tight. all i have to say is have fun sanding and dont use to much bondo (which i hate, try rage gold) or else the box might be a little stress prone to cracking etc. good luck with the finish.

 

wow. from my experience you would have saved alot of time if you would have pulled the cotton tighter. personaly i use fleece it strechs alot more. plus it bein all wrinkle on the inside is really gonna effect the sound of your subs. are you gonna do anything on the inside to clean it up?? but anyhow looks good cant wait so see it finished. are you gonna paint it or cover it woth something????

 

im painting the box the same color as my car with some blue, i am putting hidden blue tube lights in my trunk to help make it look decent.
yea i guess this is all basic trial and error, i hope it turns out decent atlease.
