View Full Version : Box + baffle wall? Done before?

03-07-2005, 02:29 PM
I have some questions about another strange idea I have.
I can't explain what I'm doing, really, so here's some shoddy 3d pics I made.

A. I start with my trunk (false floor pending)

B. I put a normal sealed enclosure in the back, subs facing the rear of car, like normal.

C. (tricky part) I then make an amp rack that doubles as a baffle, sealing off the subs from the rest of the trunk. This would (in theory) help with the cancellation issues caused by the horrible placement options of subs in a sedan.

My questions are:

1. Has it been done before?
2. If so, does it work?

Do you see:
- New way of killing off trunk cancellation?
- Waste of MDF?

ok- so you are suggesting putting subs in the trunk that face the rear between the wheel well area, then sealing off the subs in that little area by covering the rest of the trunk with a "baffle" (amp rack is a good use of wasted and empty space - you can do it if you like)

so, you are basically making a wall between the wheel well indents in the trunk. one side will be a chamber where you put your sealed subbox, and the other side is your regular trunk, but BOTH will be in the trunk still?

i dont see how you can seal off the trunk because of the 'trunk hood arms'... that would pose a problem. otherwise it might be a cool idea.

i dont know if it work or not. but it may.it is alot of work for a 'may' tho.

You got it right, that was exaclty my thought. It is a lot of work for a maybe. But then, I was already making a small sealed box for my own reasons. Sll I'd need to do is build the amp rack high enough to basically enclose the thing. I'm not aiming for perfection, just something to bounce most the front wave back as opposed to losing most of it to the contours of the trunk.

The big problem is I have two pretty heavy amps, and will definitely need a way to keep the amp rack baffle from falling over. That and concealing wires.

Blah, first things first, the false floor. I'll get some cardboard, particle board, a jigsaw, a sharpy, and a box cutter and get back to you.

ur subs look like disco balls...

I think that it would be a pain too get too the subs if need be.

Technically, they´re quadrangulated spheres utilizing 256 triangulated polygons.
I´ve made better 3d subs, but I couldn´t find any. Besides, you could tell they were subs.

The way it goes, I went outside with a huge *** piece of carboard to cout out a layout for the false floor. As my luck has it, the temperature had dropped from 50 to 30 in half an hour, and there was more wind than you can shake a stick at. Don´t you just *love* Michigan?

correct me if im wrong but isn't it bad for too much vibration to get to ur amps?isn't it supposed to move around the internal parts of the amp??i think thats why they say don't mount ur amps to ur box, on top of the fact that they could be stolen all together as one piece......not starting anything, just askin' , but it is a cool idea though.....

Yes, you´re right. It is. However, the baffle wall I have planned is going to be built like a rock.

3/4 MDF, foam, 1/4 MDF, foam, 3/4 MDF. Or I might replace the 1/4 with 1x1x3/4 blocks at each corner and middle. My amps probably won´t be seeing too much vibration.

just do 2x4 supports on the backside, and use L brackets to screw into the trunk metal, and expanding foam to seal the edges.

not too hard :p:

and vibrations arent as bad as 'they' claim them to be. as long as the amp is mounted on the box correctly (screws near supports\walls\bracing - and amp on the smallest side it fits) then you should be fine.

for the trunk arms.....fiberglass IS your friend.
