Mine is all warped and bent out of shape. I am going to Home Depot it, and need to know what kind of wood holds best and doesnt bend quickly.
Also, if somebody doesnt mind, giving me measurements of how big i should get the piece of wood.
Thanks

 

What is all warped and bent out of shape???

 

the trunk floor, the wooden piece under the carpet,also on top of the spare wheel.

 

You could replace it with MDF, but it's fairly heavy.

 

dude, its tuesday morning, and your drunk already ? Just kiddin' .
I clearly have written "wood" in the title and "wood" a few times in my post.

 

Just use the carpet to measure/trace over.

Hopefully you can get the MDF to fit in your car. I had to get mine all savaged to bring it home.

 

holy ****, did you just go out and take pics for me ? wow, if so, i feel so truly honored and appreciate it . lol
Anyways, thanks for the quick replies, I just wanted an idea of what to look for and get.

 

i dont even have one...

 

My trunk insert was also warped from a coolant bottle spill. I bought a piece of 1/4" plywood and used the old piece as a template as others have suggested.

 

1/2" mdf will work, they sell it at home depot, it should be in the same area as 1/4" board.

 

I used a piece of plywood, waterproofed it, and covered the whole trunk floor. This made the trunk floor even. I also cut it in half and install hinges to be able to access the spare. Will take pictures of it later.

 

Yep nuff said, I used MDF in my Civic when I had it. I could put an infinite amount of weight and it would/will never bend!

 

please take a couple of pics, since I want to do the same to my floor, since the subs were placed, the playwood has been bending itself. the subs are almost pointing down.

 

+1, my subs are bending the **** out of mine.

 

so, your guys subs eventually bend the plywood, but the mdf stays straight no matter whats put on it?
How much more does the mdf weigh than the plywood ?

 

Don't know...before my subs something had already bended the plywood, but the subs just killed it

 

The MDF is much heavier than that POS plywood aka garbage Nissan uses. The MDF could easily hold 250lbs +.... Your sub and box outweigh the MDF I would think.

 

I believe it is not necessarily the weight, but how the orginal is made. Because it is made to basically cover the spare, is begins to drop into the whole itself, especially if it gets wet. By covering the whole floor, the weight can be distributed evenly. I also waterproofed mine (some Thomsons waterseal) so even if it does get wet, it will not loose its shape.

 

the original is some crappy composite board, cardboard almost. it is pretty worthless. my trunk has a big dip in it right now. is it not possible to get a piece of plywood or whatever into the trunk if it is the full shape of the carpet? hinges would be fine, but would rather not. about to do this myself any day now.

 

yeah, that's what I thought. just wondering if anyone had made it happen. Home Depot, here I come!

 

On the center of the spare put 1 piece 2x4 maybe 2 on it. Basically bridge the gap between the mdf and the spare. Use the spare as support for the middle. I did this to my stock lid and it works. I have a 12" sub on it and no warp.

 

You don't have a tape measure??

 

uh, about one body wide and three bodies deep...

 

Just carry the old one in the store and find a piece of wood that is bigger.

 

u guys didnt have to take me so literally on the measurements, lol. yes i do have a tape measure. I just threw out a question. If you dont know the answer please dont comment. (dont mean to offend anyone)

 

Do you guys have a donut spare?

The full size spare should not cause the board to cave..

 

How about a diamond plate trunk liner? This is from paradox, but I'm sure there must be a super-cheap Ebay equivalent you could get made-to-order.

hmmm, i like , i like ,
but maybe ill make it out of wood. same 2 piece design though. then cover with carpet.
Thanks for the idea.

 

The factory material should be a product called masonite. If you want something thin to take the place of the masonite, I would recommend Lauan (pronounced lew-wan). It's the 1/4 inch plywood under kitchen and bathroom floors, or MDF (medium density fiberboard) would also be a viable product. Standard 1/4 inch plywood wouldn't be a durable product in this situation.

I have a full sized spare in mine, it actually sticks up slightly. I dumped the masonite completely.

 

I didn't know a full size spare was a factory option??

 

is not the weight of the subs, as to the wood moving out of place causing it to be firm on one side only, the sub leans on both sides and since its weaker on one it bends it.

I dont know the weight of my subs and enclosure

 

why wouldnt plywood be a "durable product in this situation"?

 

He said 1/4 inch plywood. A 1/4 inch of plywood isn't going to hold much weight. If you went with thicker plywood, it might do a better job. However, I'd imagine it sagging over time unless you put something under it to prop up the areas where it would naturally want to sink in.

Does MDF really retain it's form that much better? And isn't fiberboard very heavy helI compared to regular wood (cheaper, too, of course)?

 

So bottom line is, we should use MDF...cheaper, better. got it, any home depot will have that?

 

What I did is I turned my spare tire upside down. You need to raise the bottom of your floor a little (I think I used some old towels) and remove a foam square from your trunk board but it does two things for you:
1.) You can now use the 'bowl' of the spare tire as storage.
2.) The top of the tire is flush with the trunk floor so the board does not sag any more.

 

good idea, but boo! too easy! i wanna get rid of my saggy masonite and cut something else.

 

if ur just gonna do the spare tire cover i say MDF....if ur gonna do the WHOLE trunk flywood would be good too.....mdf is way stronger though.....but lke i said if ur doing the whole trunk u can use a cheaper weaker bored because weight will be more evenly distributed

 

+1

 

The term 'masonite' brings me back to my skateboarding days (ramp).

 

I don't think a full size spare was an option. I got another rim and kept a tire last time I got new ones. Now I have a full size spare. It sticks up slightly but I don't need that board at all now. A good trade off for my purposes.

Plywood will sag after a while. If you go with a thicker plywood it may work but 1/4 inch board isn't so strong. OSB (wafer board as some call it, oriented strand board as it is abbreviated) isn't a good idea. I would use MDF or masonite again. Once any of it gets wet it's going to be messed up. You could go with some sort of plastic. That wouldn't be sensitive to water, could adhere some rubber to the bottom to keep in in place. Just a thought. Pretty easy to work with and might be a little more durable. Certainly water resistant.
