hey all, i followed the instructions available in one of the stickys here for building a rear well box, and it took me most of the afternoon but it is done in a dry fit stage. i still need to test fit it in the car, trim the side pieces, and then re assemble it with glue and add the top panel to actually house the subs. the instructions were very good, save one part, where there is an incorrect angle. I noticed just before i began to put the pieces together, but there was plenty of extra from the 4x8 sheet of mdf so i rebuilt it properly. here are some pics

Looks good. Just need to finish the cutting a lil bit and it should fit pretty good.

cool box, its ported right? u dont see ported fbody boxes too often

nope it will be sealed

looks great so far.

test fit today and everthing looks good, i will be cutting the top soon, but first i am going to reassemble with the liquid nails and caulk the interior seams.

i will put up pics later, i got out the air sander and rounded all the sharp edges a bit as well as the one lip that slides under the hatch latch. the box slipped right in for me, no shimmying, no fighting, no force necessary. and it didnt budge once it was down there. I am really pleased with the way it turned out.

looks good man

were does it say on how to do a box like that i wanna also do one for my camaro

i believe it is somewhere in that thread otherwise try searching for it

Thank you man i already did mine another way i just did two boxes

all glued and caulked now- i will be getting my actual sound hardware in the next few weeks so i will put up pics of the rest of the work on the top sheet and wiring when i get the subs.

Good what subs you gonna put on it

2 12" Pioneer 800W
and an SLP 1440W amp is what im buying off a friend with wires for 300 bucks

figured id help him out and they still hit real hard so whatever as long as they work

I am also gonna run pioneers but i am gonna have the shallows

think ill have issues with depth?

got to love that dewalt quick change

looks pretty sweet!

for real man that thing is so boss. probably cuts a half hour out of any half day job

Why the magnet from the subs are big

Any chance you remmember what angle that was?

Nice box!!! I'll be building mine at the end of this month.

there are two parallel pieces on either side and one perpendicular piece on either side that are the sides of the inward cuts and what the large angled piece that rests against the forward part of the well- the way the instructions make it has the two in-line pieces at a perfect angle, except they have a 3/4 piece perpendicular between them that doesnt match the angle. I threw out the pieces as soon as i saw that it was geometrically impossible to make them flush, and started over. I didnt write down anything, i just cut from the hip on the table saw after making some overall dimensions and then used a jig to maintain the angle.

As long as you cut one piece at a time and assemble as you go it should be fairly obvious to you.

good luck!

i get my subs and amp tomorrow

i'll finally get to wrapping up the top piece and wiring some terminals in. pics to follow when its done.

very nice fit man ...great work

the guy im buying my hardware off of wouldnt wake up when i was at his house today- so i didnt get my stuff
he works night shift so its not like he was just being an *** but whatever. i will get them eventually!

looks great very jealous

alright i picked up my subs amp and wires this past weekend. i have yet to cut out the top piece for my box, but from the looks of the subs im going to need a baffle to raise them up another 3/4" because they are really deep.

My question is where do I put the t tops in the car now that I have speakers and amps back there?

I'm going to have to build something special for them.

dont the t-tops on the 3rd gen rest on the hump, in the t-top bag?

i have my baffles made and ready, and the top sheet i cut out from a cardboard template i made is really close to fitting properly. The big issue now is that the box itself sits right against the back of the well, and i need the top sheet to reach it so i can screw it down etc. but the top sheet does not fit perfectly enough yet for it to be a good fit with the back of the box. I just made my second revision to the top and will hopefully be finished soon.

finally done!
gonna wire it in later on this week hopefully, and got a new head unit too

Nice, when I was looking at the direction I was totally lost with the top cause you have to kinda wing it.
I finished my box but it's not this one, my friend end up talk me into building one that sits up angled towards the driver, much like the ones on ebay.

Is your box split into two separate chambers?

Also I will recommended anyone reading this not to buy a Amp wiring kit off Amazon.com if they can't ship in with in two days. Mine gave me a 12 day till ship (that was fine cause I had not finished the box) and now I'm look at not getting it till late October (not fine at all).

that sucks!

i bought the hardware off a friend who actually included all the wiring for the amp so im set there. good luck getting your setup running


and no my box isnt seperated

Yup. I got 2 JL W3's in mine and i had to use the top,baffles,and another finished top to fit mine.all using 3/4 inch mdf.

finally installed.

Cool hows it sound

i like everything. but the difference in the color just bugs the hell out of me. i would take the rest of the carpet that goes in the hump and pull it out and use it as the top of the sub box that way it all blends in and it looks like the subs are mounted straight into the floor.

i have black seats, trim, etc. so i figured i dont really care. it was going to be annoying to match the gray perfectly for the box so i went the simplest route of just black. sorry it bugs you :P

i havent fired them up yet i need a fuse and im going to get 14 gauge speaker wire cause the 16 on there now is trash.

i will probably need a capacitor for this in the end but i dont want to pay for one lol


its 1440W to two 800W peak dvc 12" pioneers. that draws a max of 120A, and i have a stock lt1 alt. rated at 140A, and a new battery. we will see...

Happen to kno where to get those plans for that sub box?

Yea, Here you go, click and save.
