What type of subwoofer box will fit best in the trunk?

[stoy2die4]

Any of you guys have ideas on what type/shape subwoofer box should I get to fit in my trunk. I realized that there is not that much space to play with. For sure I would like to keep my deserve wheel there and have sone space available for storage.

The sub that I bought is 10".. Good that I didn't go for bigger one.

This is something interesting that I found:

Any suggestions options are welcomed!!! Thank you!

I initially had this,

I am in the process of building a setup similar to those pictures,

hubbly bubbly,
Why did you want to change the initial set up..? It looks nice too, not so much space consuming. But probably the sub sound quality was not so good due to the fact it was just hanging on the trunk cover.. is that so?

 

[hubbly_bubbly]

The sound quality from that first setup was pretty decent. The backboard sealed around all the edges so effectively the boot was the box for the subwoofer. I changed the setup because that was built for a 10" sub and I had bought a new 8" sub that I wanted to try which wouldnt fit the cutout in the backboard.

The size of the box is important if you want to get the best out the subwoofer speaker.

What is the sub speaker you've bought? It'll have specs you can work from to determine the box size

Hubbly bubbly. Did you use a freeair sub in your first install. Did you use a different shelf or reinforce the original.

Just working out the best way to seal the whole boot.

If it's a free air sub then it's designed to install like that, it'll still need a good seal around the shelf though, plus might need reinforcing to stop flexing (as crigisback has mentioned).

Well, my amp is Pioneer 5400t and the sub that I have is JVC CS-DX25 10" 1200w max power. I know it's an old model but I got it new and I'm a fan of the old style paper cone models. I will probably go for that type of a set up and reinforce the shelf, eventhough mine is not a free air sub.
What do you think? Doable?

I do like your set up (first) and will probably go with that one. Did you install some kind of reinforcement for the shelf. My sub is 10" but kinda heavy.. the amp is also adding some weight.

I built a separate backboard, there are some pictures in the following link,

I stiffened the board with two vertical strips running the length, one at the back and one at the front.

According to the spec sheet - http://www.jvc.ru/files/installation_manual/cs-dx25_eng.pdf it requires an enclosure of around 0.15-0.16m3. Mounting it so the entire boot becomes the enclosure would give you one much bigger than that.

With a too large enclosure you will get reduced output, it won't go as loud. So you might get more get more distortion and possibly more likely to blow it because you're putting more power through it to get the level up.

So, you're telling me it would be better to put it in a box. If it's .15-.16m3, then a slim box would do the job. 40x30x15cm would do the job? That's what it looks like. Strange..

Off subject a little but have you seen the new golf, you can spec it with a sub in boot, hopefully this will be an option on the Leon too, just have a look under the car config.

Yes, it's what the speaker is designed for. 40x30x15cm would be ok. It's the total volume that's important, rather than each dimension.

Thatll be in the dish of thw spare wheel in replacemet for scissor jack, which will in turn be stuffed somewhere else no doubt

im missing my bass, big tunes aint the same without it!

Custom 8 or 10" enclosure with a decent amplifier will work perfect in a leon.
But if you need the space a unit to fit the spare wheel or the ultra flat pioneer subwoofer will fit most drivers needs for bass just as well.
