So here''s what''s happening ... I''ve measured the opening in the trunk of my 2001 Oldsmobile Alero ... approx. 16.5" (with the grey cover on covering the bottom of the trunk) ...
It''s about the same if I drop the seats ...

The reason I''ve come up with that size is I have a speaker box that measures 16.5" ... it JUST slides in through the back and if forced, will slide through the inside of the car (drop the seats) however the molding is in the way ...

So, where could I get some more room? I''m looking for 1 more inch.
Anyone take the bottom cover off (picture where the hinge is for the trunk latch, on the body of the car ... all that covering).
Or how about inside the trunk, close to the seats, that molding that''s wrapped around there ... would that help?

Looking for some ideas!

Sounds like you should chop an inch off the box. Even If you pulled the back seats out, and brackets you wont get an inch more room to get the box in the trunk.

Well like I was mentioning in the original post,
The space is there, it''s just the make-up of the car doesn''t exactly allow it ...

(This is the 2-Door Model) ...
Drop the back seats, there''s a plastic molding (can be seen from the inside of the trunk) that''s rounded and starts from the side of the trunk, travels on top and back to the other side ... that''s essentially "blocking" any way for me to push a box of that height through the back inside the trunk ...

From the trunk side, opening up the trunk,
There''s just the plastic down below that''s really in the way and doesn''t have any "give" like the rubber near the top of the trunk ...
Either way, I just thought I''d ask, even though I''m pretty sure I already know the answer to this problem.
Seems like 16.5" is the biggest.

But, I thought I''d ask, since I''m sure people have tried to put large things in their Alero trunks in the past ...

Well if you have the back seats down, the plastic trim around the top does come off. There are three or four push tabs that hold it on. You can pull them out and take the trim off. Hell you could pull the back seats out and all the trim around the opening to see if it will go in that way.


I thought you were saying the box was wider than the inside of the trunk. I have had a pressure washer in my trunk. I had to put it in through the back seat. Talk about a bitch.

Great, that''s the type of feedback I was looking for ... I had no idea that the back plastic would come off, I''ll have to look into that.


Also, after looking at the trunk opening a little closer, that plastic (on the body of the car) seems to unscrew ... I might give that a try, just to see what''s underneath (how much space) ...


I have no idea why the plastic inside the trunk is there in the first place ... doesn''t seem to "fit" the make-up of the trunk.


Anywho, thanks for the feedback thus far, I''m going to look into that late this week.

Good luck, hope you get enough room to get the box in.

So I took the back plastic off today to find maybe .5" ... nothing significant. Now I can see the metal and the make-up of the car ...
And I don''t think taking THAT off would be an easy job ...

As for the plastic inside the trunk, I can see how it moves but I didn''t take it off because I don''t see any extra height there either ...
That opening is only about 16 inches in height, which is why my current box of 16.5" can''t slide through ...

Back to the trunk opening, there isn''t any give at the bottom, isn''t much give at the top ... all I can think of now is to maybe get a piece of wood, 17.5" in height and try to slide it through ... measuring tape doesn''t really give me the confident "know it all" that I''m looking for.
Or otherwise, 16.5" it is!

Alright I went out to the car to take a look. I pulled the plastic trim off, the one that goes over the stikers for the back seats. I measured from the top to the bottom of the trunk. I got just a hair over 16.5 inches.

What is the lenght of the box? I measured across the truck also, just were its I had 16.5 inches though. From the center of the trunk there is a foot on each side that is 16.5 inches from the bottom of the trunk. As soon as the the metal starts to curve, pic below, it is no longer 16.5 inches.

You can also pull the bottom of the back seat out so the folding part of the seat will fold a bit further to maybe get you some more room.


My car is the sedan but the back seat and the trunk should be the same.

17.5" Height
17" Deep
32" Width

I appreciate you taking a look for yourself! That was neat since I wasn''t brave enough to take mine off ...

No problem. That box aint gonna fit though.

Well the width and the depth will be fine, just the height is no good.
If you don''t go too far back (as in you don''t hit that bend in the trunk) there''s actually significant height advantage (above 17 inches) and the width (between the hinges that swing into the trunk from the trunk lid) is about 38 inches across ...

I''ve taken pictures of that previously for this box maker when I was giving him ideas ...

I thought I had the height but then I realized that even though I have the height IN the trunk, I don''t have the height getting INTO the trunk.

As of right now, I have a 15" sub in a plain sealed box that''s 16.5" in height ... it just slides in, no "give" ...

Yeah there is plenty of room in the trunk itself, just getting it in is a pain. Have you tried to put in in through the truck? That plastic piece that is across the back of the trunk, were the striker for the trunk lid is, it pulls off. I don''t know if that would give you enough room either though.

That''s where I''ve measured before, which only looks like it''s about 16.5" ... that seems to be where you measured as well in your pictures ...


I have an empty box that''s 16.5" and I pretended to slide that through the back today ... even if the back plastic was off, I don''t think there''d be any height, since the body of the car is right there (hiding in the plastic).


Removing the plastic where the trunk opens, I found the metal of the car but even that looks panelled. Know if that''s removable?

Well if its plastic it will come off the car but with pretty much all the plastic trim, removing it wont give much more room.


I don''t know how your box is put together but I have heard of people making a box to the size they want, take it apart and put it back together in the car. I don''t know if maybe that would be an option for you though.

Update: I decided on a smaller box, so problem solved.
With that said, I'm on a car audio forum where the guy is going to fire 3 subs UP ...
I'll post pictures down the road when he's done ... this is something I gotta see! (I don't even know if it's safe!)

That sucks you had to go with a smaller box, but atleast it fits!

I'm not the only crazy person with this same problem ...
I was watching this guy talk about putting some audio equipment into his trunk (Alero as well, 4-Door) and he's mentioning that he's got 18" high ... even 37" across ...
I'm like buddy, NOOOOOO you don't ... you better check to see if you can even get the box into the trunk, because literally you can't go past 16" or so inches, even if you strip everything down ...
And even with the back seats down or OUT, that part of the trunk is smaller (in height and width) than the opening of the trunk (by the hatch).

After all that, he came back with new measurements and new pictures ... yeah, he can't go past 16" lol

It's weird, because I like the size of the trunk. I think it's pretty big for the type of vehicle it is but with that said, it's just not a perfect box like a lot of other cars are ... for some reason, its got all sorts of weird shapes!

Yeah if the trunk opening was a bit larger it would have been better.
