Default Stealth subwoofer install.

I have been working on installing my system the last few weeks. I figured I would show my work so far on my sub install.

The box beneath the deck is bolted to the thread where the spare tire was, which means no "smash and dash". I tried to make this a serious pain in the ___ for someone to steal.

The lid is covered in a wire mesh accross a grid of holes to provide the sub some air. This is then bolted down with eight flat head bolts through the deck into tee nuts. Woohoo! Lets at least frustrate a thief.









This weekend I plan to make cutouts in the deck for my amp and eq as well as the cap. Hopefully that will work out, as I had not originally planned to do that. I think it will look nicer when I do show people. Which may not be often with the effort it will take.

Any ideas or advice?

Wow! Thats almost exactly my idea for a sub back there lol.

Did you cut in to the foam piece that is below the carpet or something else entirely? You should totally give a run down on the general installation

I built the box to JL's specs (1.25 cubic feet). The dimensions ended up being a little strange based on the lack of height and angle of the spare tire well. I didnt bother making the box pretty, since it would be covered. That is why I dont have pictures to show.

I got rid of the foam mold altogether. Which is unfortunate because I like the flaps that fold over the gap between the seats and hatch when folded flat.

I traced the shape of the mold and cut the deck out of 3/4" MDF, same as the box. I routed out the edge to sit on the original lip all the way around. Then cut a frame to mount between the deck and box to clean it up.

The lid is 1/4" MDF and is the same shape, only it raises the height overall as the deck is actually flush with the original foam piece. With the mat over it all, you would never notice 1/4" though.

I will try to take more pictures this weekend when I have it torn up again. I admire people who do tutorials, because I am always way too wrapped up in a project to think to take pictures.

Let me know of any other questions I didnt cover.

Looks awesome! I wanted to do that with my subwoofer install, but I couldn't let go of the spare tire. I guess that's why I opted for the parcel shelf version. Nice work!

Thank you. i appreciate that. I spent a lot of time with your Flickr photo set before I started to run wire for the amp. It really gave me a good idea of what to expect and helped out a lot in the end.

The spare tire is one of those dilemmas that will never be agreed upon. I had to have a stealth install because of my neighborhood. I know that one day, whether its tomorrow or years down the line, I will be very upset that I dont have a spare with me. I will just have to weigh all of those days of listening to a decent stereo to that one day of extreme inconvenience.

The more variations of installs we have, the better off our community will be. So lets get them going people! Cheers!

Hey TrebleStauter,

I'm looking at doing something like this later this year. What was the dimensions of the box you built, what size subwoofer is that, and does the sub being covered like that effect the sound much?

I will need to look up the dimensions, sorry.

That is a 12" sub. It needed 1.25 cubic feet of interior air space. So, essentially you just need to find out what the sub you are using requires, then build the box to the correct dimensions.

The lid has a grid of holes where the sub is located, so it is basically like a grill. It allows air to pass right through it. Even with the mat over it all, I can feel the air flowing right through it.

I worked my ___ off this weekend in 90+ heat and 110% humidity to finish the amp/eq/cap cutouts in the deck. I will post pics once I get them.

My first impression would be no. A 15" would take up too much of the top deck space to be mounted along the spare tire well angle.

If you havent looked, the angle that the spare tire is mounted in the trunk is pretty hard to work with. It didnt allow me much space for a 12" let alone a 15"

That said, I know that a lot of manufacturers are making very shallow subs these days. I still doubt you could get the depth from bumper to rear seats to mount it without the basket (or box) hitting the well.

I would sure like to see someone do it though! Good luck.

Thanks. I had forgotten about this thread. Here is an updated pic from last summer, Not the best photo, but shows what has been added.
