I am looking into at building a sub box for my bird, I want to be able to strap my T-tops in place like intended. I will probably run one quality 10" so I am thinking I can recess it a little.
I am thinking I may want a small storage area on one side deep in the well for a small box of detailing products, a quart of oil etc....

 

My t tops laid flat behind the rear seat, NOT in the luggage well like in a 4th gen. No reason you can't run a sub there.

 

that's not the route I want to go, I like my T-tops strapped in place where GM provided...

 

I feel like we're mis-communicating. GM intended them to lay flat, behind the rear seat, NOT in the luggage well. Now I'm certainly down if you don't wanna do that, but the reason I put it out there is because in your first post, you said you wanted to keep 'em where GM intended. If you wanna put 'em in the luggage well, more power to ya, but that's not where GM intended. .....and laying flat, leaves the luggage well open for a sub and a few other small items like you mentioned.

 

I agree with Abubaca - sounds like there isn’t a meeting of the minds on this. Below is a picture of the factory t-top bag in a thirdgen hatch. The bag lays flat on the hump over the rear axle. This leaves plenty of room to install the stuff you want in the well area at the far back. My car in the pic below has a factory well lid that hides the recessed area. You could easily fabricate a flat board with a sub to look similar.

 

I built a box for a dual voice coil 10" sub that fits down in the rear storage well. Made a carpeted cover board with a couple ports that lays flat over the ledges on each side. Looks good and a 10 is plenty with a good amp. I think I posted a couple pictures on here some years ago for that.

 

sorry guys, there's definitely a little confusion! I see a lot of sub boxes made that mount too high and obstruct the T-tops "laying flat" as designed, I want to build a box that is recessed enough not to interfere with them.

 

I think there is definitely enough room to do that, especially with a 10".

 

This is a baffle board currently, like Tom3 had suggested. Supported by ledges on either side of the “trunk well”

plan is to convert to a ported sub box. 2 10” subs (isobaric push/pull).

lots of room for t tops, even after conversion to sub box.

 

Custom made box for 10" sub and it doing the job

 

Slowfox, that looks really good! I've considered something like that myself. I've got the cnc router files for an 8" box. (I've got a big 3 axis router at work). Was gonna carpet the box and just cut out the plastic. The way you have the whole thing molded looks really sharp!!!!!!

 

very nice. Do you've any details on this enclosure?

 

jimmylev, what details are you thinking of?

 

Is the rear of that enclosure boxed(?) as well, or is it just the front and the car body is the rear?

 

 

My old 84z, though i used the trunk well as a box since those old CW's are free air subs (12"). Used a hinge from a busted factory lid and the lock from my stock lid.

 

Here is one from about 20 years ago. 1/2" mdf. 2 10's. Doesnt interfere with the t-tops. I've still got it but its due for an update.
