Building a false floor for the Mk4

[stuart_hatch]

Ok, im wanting to build a MDF false floorfor the boot of my Mk4.

I went out to look at my boot to take so mesurements and its so unflat, i dont have a clue how its going to work?

Will i be best removing the carpet from the boot floor and building a MDF base and build up ontop of that?

Please help, my sub looks crap in the polos uber deep boot!

(im going to build the false floor to house the sub and my amps) also prefeably leaving my boot still usable

I did this in my MkIV, took out the carpet and built a MDF base with a hinged middle section big enough to access the spare wheel, I then mounted the amp in a tray under the floor, which had a cut-out the size of the heat sink on the amp so it sat flush with the floor.

my sub box then had a flat base to sit on, and could still be removed if I needed the boot space. IIRC you can get some charcoal carpet from car audio dealers that matches the existing carpet really well.

Hope this helps, sorry, haven't got any pics, and the car is long gone!

I made a false floor for my boot, and, all sympathy to you mate. It's not easy.

It took me ages to get it right cos it was my first time doing a false floor. All i'd attempted up to then was simple sub box's and acoustic parcel shelfs.

Anyways, the best way to do it in my opinion is to, as you say, remove the carpet completely. Take everything out the boot to give a clear area to work with. Then use small blocks of wood at the level required to get the base to the level you want. I used a large spirit level to get the blocks almost level. I say 'almost' cos it's not perfect but i don't think anyone would be able to tell. So start off with them too high so u can trim them. I secured mine with hot glue to the boot floor.

After that you should get a large piece of card or cardboard and get the rouch shape you need, again slightly too big so you can trim it. If you're gonna hide the amps under the floor then again the bit doesn't need to be perfect. Then you'll need to attach some small side supports for the top level to sit on, you should probably have some spports spaced out on the floor to give the mdf some support and make sure you have plenty of space between the two floors so as not to cook your amps. You might want to think about fans.

So that's a starter for you. If you get stuck or have any more questions let me know. You haven't said what your gonna do about a sub-box.

Here is what mine looks like. It's a bit different as mine is just a raised floor. I wanted to use my spare wheel so my amp is hidden behing the sub-box and faces the back seat.

Cheers for that, i still havnt decided what to do about the sub, i was thinking of having it in the boot fllor and mayby making a cover so i can put stuff in the boot still, but now ive seen yours im not so sure!

I made a framework for mine - 2 or 3 bits of 2inch x 1 inch pine that can go all the way across the boot. nice and firm. down each side of the boot I put some additional pine to mount the framework to - seems to be pretty level to me.

then the mdf / ply can sit on top.

just get loats of card and make a template then cut it out of mdf and remember when triming mdf for installs your better off cutting to little then to much
