Fibreglass Install...

Four seperate boxes might be easier to deal with. Before tackling a project like that one in the picture, I would really plan out every step before I even start.

I would start by stripping everything out of the car, lay all the wireing, Including a couple extra sets of RCA's, you never know, nd then start figuring out where everthing is going and what it going to take to get you there.

A project like the one in the picture is not difficult at all, but it was time consuming and it required a lot of preplanning.

 

ranger i'd like to do a fiber glass box in the shape of my spare.would useing an actual tire be recomended for the shape or will there be some sort of cemical reaction?

my tire sits inside my truck,and i'm looking for a stealth install again.i used to have 2 round boards sandwitched between my spare when i had a round 10' sub. it had a nice impact and was 100% invisible. it would have been a hastle to take it apart in case of a flat.plus the sub was a dud an i replaced it with my L5.

i'm sure the internal vol would match my kickers specs.close enough anyways.L5 10'.i was thinking of useing an empty tire. or one with the rim cut out,and use that area.i do have a spare.it's on my roofrack.

i know blah blah blah...what do you think.?my local shops told me somewhere in the 800 dollar range for something like that.i'm sure i can do it for a fraction of that. i do have 4 days off a week.so time is not a prob either.

 

Um...you can cover the tire in masking tape and aluminum foil....Well I've seen it done many of times...just cover what you don't want to get resin on with tape....a couple or a few layers to be sure

 

sorry Ross....its Pedro's fault for thread jacking

 

I would stay around the 1.5 cu ft range. This way if you end up slightly larger or slightly smaller, no harm done.

Pedro Quiroga, I need to think about that for a minute

 

i could not agree more and i would get it all playing first . maybe put some wood boxes back there first in about the same size and location . to make sure you are going to like what you hear. thats an awful lotta work to have to tear pack apart if it sounds like poo. been there done it. and have the t- shirt to prove it. lol

 

Ross said..
How do you work out the size of the boxes? I know you said 1.5 cu ft but whjat dimensions is that roughly?



I was wondering this question too.....How do you fugure cu. ft. when doing fiberglass? Do you just make a rough estimate?

Also like in Ross' case, if you are mounting multiple drivers, should you make a separate compartment for each driver?


Sorry Ross....don't want to jack your thread, just asking a similar question and adding on....

packing peanuts work great . take a box that inside dimentions are 12 by 12 by 12 thats one cubic foot. fill your enclosure with the peanuts. remove all the peanuts and see how many times you fill up that one cubic foot box. for 1.5 cu ft. you should fill it 1.5 times. if you do not fill the 1 cu foot box all the way up measure the sapce left subtract if from the 1 cu foot and that the volume. volume is interior Length by width by heigth divide by 1728

 

I guess what I mean is this....

When I build a box that is 12x12x12 I know it is 1 cubic ft......But if you were building a glass enclosure and it had all kinds of contures in it, that would make it hard to figure exact cu. ft......Correct?

So let's say I have a driver that needs 1.8 cu. ft.....and it were to go into the back of let's say a honda civic hatchback.....If I as gonna make part of the enlcosure be the spare tire well and then come up and flow around some parts in the rear. Maybe the sides curve and dip.....If you mold that on the bottom to conture all those places, how do you get a real good idea??

If you mold the bottom and sides, then pop it out, turn it upside down and fill it with those foam peanuts, what if it is way off?? Do you scrap all that work that you just did with the glass resin and mat, or do you try to just guestimate before and and hope it is close??

Again, Ross.....I hope this is info you are seeking too....if not, I can start another thread.....I was just curious after recently (here and the Dec. issue of car audio) seeing how fiberglass stuff is done.....

sorry ross. just wanted to ask a quick question bout fiber glass.

 

i would try to measure what i had before so i could get close.
