Started on false floor today, pics inside, more to come as I progress

[bikinpunk 10+ year member]

I started the install today. My goal was to be able to lift top & bottom layer up so I can get to the spare tire. I cut finger holes in the bottom layer to get my hand in there and lift up on it. I was originally going to go with some sort of hinged setup where I would take the top layer off, and the bottom layer would use door hinges to get to the spare....buuuuuuut, I realized that other than "cool" factor there's no reason to do that since I can easily lift the bottom layer up high enough to get the spare out. For the top, I will likely secure it by using 4 screws, in the top & bottom corners. The sub-box will go back in the very back...I'm probably gonna have a very tight squeez, but it should go. The box is 14" tall, the floor will be 3.75" and the total trunk height is 18". :xyxnervou

I finished cutting the two layers and getting the bottom one installed with my 4-channel amp installed as well. I'm waiting on my 1000/1 to come in from warranty.

I would like opinions on the fan I'm using. It's a 4" computer fan I got for free. It runs kinda loud, but I don't hear it with the rear seat up. It's a ball bearing fan I believe as well. I got two of 'em for free when work was trashing some, so I thought I'd give them a shot before I buy new ones. I plan to use 1/4" plexi to showcase the amps, and one fan pulling the air from the inside, but I might use two?...

Here's a couple pics:

Bottom layer cut, with with hand holes drawn out

I'll clean up the wiring some (but not much) when the other amp gets installed. I'll keep this post updated as I progress. Hopefully I'll be done by Saturday night. My biggest issue is getting the top layer routed for the plexi.

Gonna be badass man, kinda wish I had a smaller box so I could do the same thing. I'll be following closely. Good luck.

Anyone care to advise on placement of the fan/fans? I'm not sure if I want to have a fan pulling air out of the false floor, of if I want to have the fans standing up and blowing onto the amps from the side.

You want to pull hot air out of the false floor.

I was reading something about one fan blowing into the chamber, and then on the other side the second one pulls the hot air out. I think that sounds about right...

I'm sure there's other ways to do it though.

I like the fan you have cooling your false floor.... //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

It's hard to see from my pic, but I have a space on both sides of the new floor where the trunk goes out a little more at the very back...I went against making that part go with the rest of the false floor because I was thinking I could use it to put something that needed to stand up. Those sides also will act as an escape for the warm air. If I do go with them standing up, I'll have to buy smaller fans. Should I run those fans right next to each other pushing air from the same point (series):

...or should I have one fan pushing onto an amp, followed by another fan pushing onto the other amp (parallel):

Update: Didn't have much time tonight after work, but I did get the bracing in place. I think that should be plenty. More to come tomorrow...my back hurts. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Sorry if I missed it, but are you going to do the subs rear firing right behind the rear seat there?

 

[RollinGTO 10+ year member]

interesting..

 

[dyabolical 10+ year member]

One fan pushing, the other pulling would be my suggestion.

 

[bikinpunk 10+ year member]

I'm going with 2 fans pushing through the "channel" that the amps are in. The channel will help direct the airflow past the heatsinks. Here's an idea:

On a side note...

this is getting expensive. So far I've had to buy plexi, router bit, full sheet of mdf, wood glue, silicone, and extra jigsaw blades. When I started I was thinking it would only cost about $30...

That's how I had it originally, but since I'm taking the amps off the rack which was right behind the rear seat, I might fire the woofer toward the cab of the car.
