I want two 12" JL Audio subs in the Skoda, just like I have in my Chevy Suburban, because I love the sound of those. But I don't want to... Who am I kidding? Not even myself! My wife won't let me use up any of the space in it! So I thought about cutting an MDF plate to size and put that instead of the original, foldable upper floor (with the lower floor removed, speakers underneath the MDF plate and a solid metal plate with tons of holes in it so nothing falls down). But maybe the original foldable upper floor is solid enough for the subs? Has anybody tried?

Don't know about a sub but I regularly carry over 100kg on my upper floor for weeks on end, with no damage or sign of bending.

Not bad, thanks! Then I only have to find out what material it is, and if I can cut the holes without problems. I'm guessing that it may be some kind of waterproof MDF, but I'm not sure. I'll better loosen a bit of the carpet on the underside for that, so my wife doesn't see what I've done...

I would go with your original plan - get a new piece of wood to use for the flooring / speakers. Then when the wife is less than impressed with your handywork you can return the boot floor back to its former glory!

He-he. Thats's the thing. She's never impressed with stuff like that because I do it when she's out, and she usually doesn't see the difference! I'm actually pretty good at conceiling audio equipment (both in the house and the car). You should see my attic - 10 receivers with hidden speaker cables to ceiling speakers and regular speakers in almost all rooms in thhe house!

how about going down the route i did, its changed a little now but same idea!

Thanks a lot, that was very nice! I actually thought that wouldn't work because the bottom floor seemed to flimsy. But if it works, it works. I think I will follow your lead. One question, though: Would it be possible to see a picture of how it looks like underneath there, with your padding and stuff? It would probably help me a lot on the way. I'm guessing that cramming a couple of 12" there would be too much, but do you think it would work with at least two 10"? My sweet spot is 12" but I'd settle for 10. 8 is a bit too small for my taste...

Btw does it change the sound much when you close the false floor? Knowing my wife (after 20 some years I should know her...) that will be the way my car will stay!

Perhaps my best bet would actually be to put a sturdier MDF plate instead of the underfloor. That way I can fit any size woofer I want to in there?

You could say to her "I am MAN!!! and I will do what I like to the car as I see fit!!!"

This more than likely will be followed by "yes dear :("

i will get some more pics tommorow, i made a box 12mm ply i think it was (carpet is stuck ontop), To keep the spare in there aswell the biggest i could go (keeping the ply solid) was 8 inch but they sound bloody good for there size! when you close the the floor (as mine normally is) it still has a massive amount of bass but not too much, even past wetsuits, surfboards and lots of gear, although i have upgraded the rest of my speakers which might help too!

DBP, that's why we men always gets the final word, which usually is exactly that. "Yes, dear..." Mostly because they can go longer without sex without going bananas than we can!

Jamesk656, thanks! Looking forward to seeing that. I actually thought that you had used the original plate there, but I understand now. I think I may do a variant: Use the original lower floor for a couple of speaker grills and have it laying over a custom made box. Hey, maybe I'll even be adventurous and exchange the spare tire for one of those cans of air and foam that newer cars use?

Keep the spare tyre..... imho these modern cars with a can of foam are not much use!

Oh, and I thought every modern was better... Seriuosly I haven't used a spare tire for at least 10 years, maybe more. On the Chevy Suburban I've never used it, but I once hit a sharp stone edge with a Mazda MX-3 we had and ripped up the right rear tire. I shouldn't have tried to race that guy...

Edit: Another argument for that is that the spare tire in the car is the original, and it obviouslyt has never been removed and used. Even the tools are in the sealed plastic bag inside the styrofoam container.

While they might not be used much, if you have proper trashed the tyre, then I would much rather have one in the car ready to pop on, rather than having to wait for a recovery truck/etc to come and rescue me. I have used my spare tyre - got a piece of glass in the tyre (broken beer bottle in the road). I doubt a can of foam would have fixed that. Still each to our own.

Plus if necessary I pop on a spare tyre at MOT time. No point shelling out for new tyres if the old girl fails for something serious. One of my mates made that mistake with his old Primera. 2 new tyres, and then it failed the MOT, and ended up in the scrap yard shortly after.

The supplied tools are probably rubbish, I carry a torque wrench, rather than having to battle with the silly wheel brace which is provided.

Well, I have a large pipe handle which comes in handy in a fight as well... As for recovery trucks they are not a problem here. Every little hamlet has one, and it's free (well, it's part of what I pay for in the insurance). I have to do a bit of thinking when I see the pictures of Jamesk656's setup.

Jamesk656, any pictures coming soon? I'm about to get some subs this weekend.

ahh yes sorry been busy at work lately! ill empty the boot out tommorow and get a few for you!

James, something tells me that you're a very busy man! So my plan for now is to use two Alpine Type R or S Slim Mount and first simply cut out two MDF plates that I can put in instead of the lower floor (one long plate in the front, and a shorter one over the "tool kit" placement, then I won't have to change the whole thing when I experiment, I can only do the rear part), and make the space airtight with rubber gaskets and gaffa tape (don't laugh - I have actually done that before, and three layers of gaffa will actually air proof a leaky subwoofer box very nicely!). I'll have the subs mounted on top of the plate, without sinking it into the wood, so it goes down in the space below as little as possible.

Then I'll listen to that. If I'm not satisfied I'll take out that tool kit and build a box the same size as that and split the two chambers. That should at least work without any problems. Does that sound like a plan?
