Plywood? mdf stuff? .... i don't know what to use

d_warner

That's gonna depend on what you're using it for. Are you mounting amps, supporting an enclosure, or just making a floor to haul groceries on? Each material has its good and bad qualities.

MDF - Strong yet heavy. Great for enclosures and ease of use
Plywood - Strong, lighter, splinters when working with it. Not quite as strong as MDF.
Thin carboard OEM flooring - Lightest weakest, OK for hauling groceries and covering in vinyl to make it look pretty.

Like I said. All depends on what you're doing. Keep in mind, MDF comes in a variety of thicknesses. I've seen 1/4" all the way to 1.5".

it's going to be supporting my box and an amp

I'd go with at least a 3/8" MDF. Easy to find at Home Depot. You can even go with 1/2" MDF. One thing to remember is your spare tire access. It might not hurt to support your box side (front) of your trunk with 1/2" and do the rear of the trunk in 3/8". MDF will definately hold the weight. Remember, it will also add weight to the car.

The nice thing about MDF is that it is flat. If you go to Home Depot and check out the plywood and particle boards they are almost always warped.

thanks for your help

You guys are using the wrong kind of plywood. There are varieties much stiffer and lighter than MDF. But also a few times more expensive. What really nice is how it can hold a screw. Ever mount a sub in MDF and have to take it out for some reason? Notice how much less holding power the screws have every time you take them out and reinsert? Big problems with MDF for any parts that will be moving around or need to be screwed together.

My floor is made out of some variety of hardboard, stiff, but pretty light for the size. You don't do any screwing into it aside from a few supports on the sides.

Could someone post a write up on making a false floor? I wanted to make one with my amp behind some plexiglass, but I have no idea how to do that. Any help would be appreciated.

I used mdf on my old system and it held up great and looks good when painted.
