kevin, here is a rough rough rough diagram of what i am doing. basically the sub box (dunno if it will be an actaul mdf box yet) against the back seats. The false floor will be many pieces, but there wont be gaps or anything. I plan on putting one or two 2x4's and mounting those to the trunk floor, then the "false floor" will be screwed to those. you can see where i plan on putting the hinges and such, I have to test with a piece of something if lifting that board up with the hinges will allow me enough room to remove the tire, so like i said this is rough rough, i havent measured anything yet.



those two rectangles are the hinges. the dotted lines show the piece of the false floor that will be the one that lifts up.

the rectangle where it says kicker and JL MIGHT be plexiglass, im not sure yet... trying to decide if it would be more "stealth" and better security if there wasn't plexiglass there.

I did this with hatchbacks so it wasn't an issue.
in sedans I just move the enclosure back against the rear seats, and don't cover the tire well..

I have been following this thread because I'm planning a smilar design for my Accord sedan. I haven't removed my sub box yet, but I don't think there will be room to have the sub box roll back if you are mounting them up against the back seat (I believe that is what you said you're plannin on).

What I have tenatively planned is making a false wall that would serve as the face of my sub box with the speakers facing the rear of the trunk. That way when you looked into the trunk you would just see the two speakers and none of the rear deck or anything else. I think I will make my false floor out of two pieces with the hinge at the point where the wall is. That should allow me to lift up the floor from the back of the trunk in order to access my amp. I'm also planning on some plexiglass just above the spare tire area with my amps mounted above the spare tire (if there is enough room) upside down and back panels removed to show off the circuit boards through the plexiglass. I'm not sure where I will put my crossover or fuse block, but it might fit in there too.

It should look pretty nice when finished off with a little neon to accent the circuitry and all. This is a pretty ambitious project for my first custom install, but I think the plans are finally starting to materialize. I'm still trying to determine what type of material to use for the floor. It is a pretty large space so I'm unsure what thickness would be sufficient to prevent any warping and be able to sustain the weight of the amps pulling down on it from below. I'm thinking MDF, but I don't think I need something 1/2 inch.

Keep us posted on what you plan to due and include some pics if you can when you get started. I will be sure to do the same.

you hinge the board at one end, and mount the hinges to the car so the board opens like a big door.
you screw teh bottom of the sub box to the tire well cover, so the back of the sub box is right at the hinges. then you just rock the box backward onto its backside, and that opens the tire well up.

so basically the only dilemna in that solution there is will the sub box clear the roof of the trunk when being rocked back?

I used to do this in CRXs all day long.
hinge the forward edge of the tire cover board, then attach the sub box to the board, so you rock the box forward and that exposes the tire.
very easy to do.

well im glad that it's possible, but i dont quite understand, can you please go a little more in-depth for me? thanks

sure you can do this.

I'm going to post some pics of mine too soon. Good Luck, btw.

mine is a 99accord too actually

its a 4door ex

cool we can share a thread

i will take some pics when i get a chance, ill try to find another honda trunk...my sub box has a few screws in it and stuff and i dont really want to take it out until i start the project which is april 4th for spring break.


gonna have to make a new sub box. might do a custom box with some fiberglass to get it as far back as possible (my trunk gets pretty low as you go towards back seats) its about a foot out from the back seats right now with the kicker behind it :-/ thats what i dont like.

anyways the main purpose i want to do a false floor is for security, so obviously the reason i cant just do a hinge is because anyone could just lift it up. I need to create some sort of security feature for it. or just something tricky and time consuming to figure out.
anyways ill get on those pics will
