Custom Lift Back Hidden Sealed Woofer Box

[TinyGiant]

You will Need:

3/4" MDF ( I got two 2ft x4ft sheets)

Drill (Small bit to pre drill screws and large 1/2" bit to start the band saw cutting the sub inset out)
Gorilla glue
tape Measure
Screws 1.5" works nice
Square
Mounting Ring
Auto Carpet
Elmers Spray Glue
Terminal (so you can connect the wires to the sub)



Just the text:
1. gut out the back.. take out the spare.
2. Trace the spare cover (I cut out the nubs that normally would slide in.. it sits in alot easier when you can just drop it in.
3. make sure it fits nicely.
4. Find out what volume you need for the sub you purchased. My sub needed .675 i believe .. so i made it about 19"x7"x14" (those are outside Diameter) Dont forget to find the mounting depth of the subwoofer too so you can make sure the box is deep enough. and add the 3/4" from the inset ring. i would actually reccomend trying to double ring the sub so you have a whole 1.5" from the woofer to the flat of the shelf. so the woofer doesn't hit the mat when you throw it back on to hide the woofer.
5. trace the outside diameter of the woofer to cut out the inset.
6.Drill a hole so you can get the band saw started
7. Cut out the hole.
8. Affix the Ring underneath the top so that the sub is counter sunk. I glued and screwed that ring on. (being sealed is key)
9. Build the box (glue all sides) Screw sides together so its super tight
10. Wait until tomorrow and then shave all the glue that expanded off.
11. get some Carpet for the interior or top of the shelf.
12.Spray down the whole top of the unit then lay and smooth the carpet down..
13. Cut the circle out so you can mount the sub.
14. Get a terminal and trace the hole you need to drill so you can insert and screw it in.
15. Connect the wires inside from the inside of the terminal to the woofer
16. Screw that sucker down and get ready for the bump!


Hopefully that will do it for you guys that's what i can remember from the first time this was posted.

Gut out the trunk

Trace the tire area cover
*Note .. didnt know this until i was done .. but dont bother to trace the part that slides into the little cubbies in the back. just round those off with the jig saw.. if you put the nubs in there you wont be able to get the box in the trunk with the bottom chamber attatched... which will be necessary.. this way you can just drop it in.

Cut and make sure it fits

Trace the outside of the sub woofer this is so we can make the woofer set in the box rather than on the box.. you can see on the picture the placement of my 10" circle
http://i40.photobucket.com/albums/e208/3mrhythm/IMG_3009.jpg

Drill a hole somewhere on the circle so that you can get the jig saw into area to cut the circle out

I salvaged the front of a woofer box i had for the mounting ring.. but you can usually order a ring or look at the manual for your sub to get the mounting


you can also take the box the woofer came in.. alot of times they are made so the woofer sits in it.. take out the carboard and trace it to make the circle it mounts in.

After you have that cover it in glue, position it and screw it down.. it helps to drill some small holes before you screw it in so that you dont expand the MDF
http://i40.photobucket.com/albums/e208/3mrhythm/IMG_3011.jpg

here is what it will look like when its

mounted
http://i40.photobucket.com/albums/e208/3mrhythm/IMG_3012.jpg

Once you have the ring on there assemble the sides and bottom ofthe chamber from the wood you cut before..

glue all touching edges before drilling and screwing.. that way they are sealed. when you get the box made you should use the glue like caulk and do all the seams on the inside to ensure a good seal.



Then i set the sucker in there

next step will be heading to Radio shack to get a wiring terminal.. and then to a craft store for spray glue.. then to the local auto carpet store to get enough carpet to cover it.

I'm hoping that there will be enough weight with it all on there and padding with the carpet on there from keeping the box from hopping.
also there is about and 1" below the box so you dont have to worry about it vibrating the bottom...

at first i was considering using that hand bolt they use to keep the spare down the lock the box to the body... make it really resonate.. but i figured it wasnt worth the hassle

then when that is all set its time to install the amp.. probably under the drivers seat.
Thanks guys! thanks to Boyd too for the inspiration!

Final Pics:anyway.. here are the pics:

Subwoofer... where is it?
http://i40.photobucket.com/albums/e208/3mrhythm/IMG_3028.jpg
wooop there it is!
http://i40.photobucket.com/albums/e208/3mrhythm/IMG_3029.jpg

lol i had to tilt it because i stripped a screw and had to drill re screw the woofer down to seal right

depending on the throw of the woofer you might want to counter sink the woofer a little more.

found the old thread on cache

[The Architect]

i think im going to be doing one of these very soon.

I plan to only use one SX12 and make the whole top out of Plexiglass though, I love seeing the subwoofer move.

Cant Wait, thanks for the write up.

[TinyGiant]

np :)

I thought doing some sort of viewing window or something ..but decided i wanted so if kids looked in the back.. they wouldnt see the bump :)

[The Architect]

i still intend on using the hatchback cover to block all view to passer by's, its mostly a selfish love of watching the sub do its thing. I dont think many other people enjoy watching a speaker go up and down but I love it haha.

[TinyGiant]

I put the mat over mine.. i dont keep that black shelf thing n there.. because i need to put the dog crate in the back twice a week...


I was considering throwing another sheet of MDF on top though so that the woofer has more throw room.

Orderd my Jigsaw, waiting for it come in then I'll be attempting this, thanks for the DIY

[TinyGiant]

I made some modifications today..

I went to my parents house and found an old Bandpass Plexi front that went to an old box of mine.. decided to dremel the heck out of it and incorporate it into my box to jazz it up.. thoughts?!

[djgoodonya]

I love the changes you made. Very nice. Totally inspired. And cargo space is a must since I have my goalie bag stuffed in the back constantly.

[PHXDEMON]

Looks good.

[DerKaiZeRs]

Nice :thumbup::thumbup:

[TinyGiant]

Anubisx99 blessed me with a new acrylic plate.. so i decided to cut some felt flames to put under it :) here is the new look

[TinyGiant]

new update :)

[TinyGiant]

its come a long way in a short 3 months lol

[brianb]

Nice. Where's the amp?

[TinyGiant]

under it all well under and on the left side

[skigil]

I'm so glad you reposted this. I'm finally getting around to installing my sub, amps, etc. this week. Looks like I got almost the exact same Pioneer head unit as yourself. I purchased the DEH-P500UB, it'll be here Dec 24. I'm super excited to install it. It looks like the weather will be perfect for an installation like this.

Just out of curiosity, do you like your 4000?

[TinyGiant]

i returned that HU like 5 days after making this post. I got sick of it disabling the control of the ipod on the ipod itself... it takes forever to scroll for songs on the HU..

i went out and bought a touch screen in dash dvd for 100 more.. check my garage you'll see the new pics and what i have done since..

[skigil]

That's the only down side to a HU like this. I've heard the 500UB allows you to use the iPhone as the controller....we'll see.

When I was on these forums last, I was installing my 5.25" Polks in the front and my 6x9 Polk's in the back....a little elbow grease and a hacksaw later, I have 6x9's in the back. Now I'm finally finishing up my install with this head unit, an additional amp to power the speakers and a sub/amp.

(but really, I'm looking to do a CarPC in the long run......shhh, don't tell my wife)

I'm hoping to add the pictures of my install to my garage once I'm done.

I like what you've done with your car since I've been here. I haven't been here in a long while and it looks like they had a server crash, is that right?

[TinyGiant]

yeah the site was attacked and we lost a bunch of stuff.. this i reposted after the hack .. so its pretty much up to date

as far as a car PC .. you could get a mac mini .. they are super small and you can get them rather cheap.. then get a cheap indash dvd and throw the video into it.. :)..idk if a touch screen would work with it though.. maybe

[coheed]

Tinygiant could you have fit another sub and an amp in there? Like so....


And about how much mounting depth is there?

[TinyGiant]

think it was about 7.5" max

I could have fit another sub if i wanted to.. one 10" is MORE than enough

everyone considering needing two subs should hear this thing.. if you want everyone outside of the car to hear you sure go with more subs.. but the single 10" can easily be deafening if you set the levels right.

[coheed]

Do you have any pics of how you ran the wires?

[skigil]

TinyGiant is right. I just got done doing this and a 10" is a perfect amount of power for this tiny car. I did have to mess around with my levels, but now my stereo sounds a lot better!

Thanks again for reposting this.

[skigil]

Oh, and my amp is underneath the box as well.

As for wires, I ran power on the passenger side of the car and RCA's down the middle (to the amp for my speakers under my passenger side) and down the driver's side (to the amp for the sub in the trunk).

[coheed]

I was actually wondering how he ran them into the box. Like if he cut out a hole and rubber sealed it or put a metal terminal and sealed it.

[SilverBack]

Totally feeling the giant carved-out Toyota logo :bow:

If you want, you could punch it out a little more by painting over just the logo itself a frosty translucent white, then mounting a few green LEDS under the logo so it glows at night.

Got the idea from my computer fan

Great job so far

[skigil]

I drilled out a hole for a terminal. I still need to glue it in though.

I just kept taking more out of the hole with my jigsaw until the terminal fit snuggly.

[TinyGiant]

i have trouble taking a good picture of it lit.. its really bright .. the stupid camera just wont pick it up. I have 4 LEd in it already. it looks quite awesome i must say :)

[pennyracer]

some have seen mine but maybe others would like to this also http://i214.photobucket.com/albums/cc74/boydstir2291/myyarisbackenclse-3r.jpg

That looks sweet. Great install

[TinyGiant]

gave in and finally went blue :)

[custom Lftback]

haha, looks great chris! I like it much better imo

[TinyGiant]

next I might switch the lighting over to blue too.. lol


I painted the speaker grills on the front doors the same blue and plan to do the grills on the rear the same too.. I painted the access pannels for the tail lights the same blue.

next i plan to find a way to paint a ring around the front side vents in the same blue. then i should be done with painting. other than I really want to do the bezel around the shifter in the same blue.

we'll see how ambitious i get.

I really hope i get my c-one replica hood back soon :)

I bought 2 alpine type E 10" 300W RMS subs and a 600W RMS 2 channel alpine amp and I have to get rid of it because it's TOO loud. It leaves my ears hurting when I get out.

I plan on starting over with something very small and much more modest.

[TinyGiant]

yeah one 10" its more than enough in the yaris.

instead of downsizing you could always turn down your gain on the amp and the bass on the HU

[Y@R15]

looks good but why not on the door itself so you can still pack crap in tha trunk? but i love the idea looks really good.

in the door?

my woofers setup is in the floor so its no different than having the spare tire cover on.. doesnt look like anything is different if i have the rear yaris carpet on it. didnt lose any space at all for storage.. other than the spare of course.

[yaris2010RS]

that is so perfect!! where did u get the logo carved out?

[gstein7346]

I like your yaris and what you have done with the trunk enclosure. I am planning to do the same with a 12'' rockford fostage punch 3. I am thinking about using these specs for the box portion. 12.5x12.5x12.5 I havent measured yet but do you think that from the traced peice for the replacement trunk cover has enough room from there going down to the frame to clear 12.5? Besides that, does your box hit the frame? or is it mid-air? Should I recalculate to make it so that it Rests? Also did you carpet even the under side of the enclosure?

[gstein7346]

Ohh my dumb, I forgot the sub is 12 inches lol
