Installed custom 8" sub box

peleincubus

Can the op please update this thread. This is exactly what in looking for. If I could get the information I would HIGHLY appreciate it.

Thanks

you can use my dimensions - they are the inner dimensions. i used 12mm MDF which i know is thin for a woofer box but you really sacrifice box volume with thicker MDF. Using 12mm does require some precision when using screws as it splits easily.

It is the biggest sealed enclosure you can fit in there. In the end, i had to cut a slight slope into the box to allow a perfect fit with the lid attached.

If you decide to drop the box part into the cavity, then screw the lid on inside the vehicle rather than assembling the entire thing outside of the car you might not need to cut the slop but it will be annoying to hold the box up perfectly level and screw the lid on perfectly.

The reason for the slope and the direction of the slope will become apparent when you have a look at the cavity - it's not a straight up and down affair.

Do you have Bose audio? If so, the amp will need to be relocated.

Also, i am running a single Kenwood 8" woofer. The only way i can see dual 8's fitted is if the OP built a free air setup - ie, just what you see in his pictures and nothing underneath. You won't fit dual 8's in my box. In fact, the width of the box barely fits the woofer!

For the lid, use your boot mat as a template then jigsaw it out as a starting point. You'll most likely need to do a few trial and error fitments and trimmings before achieving a perfect, snug fit. Goodluck!

Thanks man. Do you think if you only used one 8" sub that you could use the other area to somehow install the amp? I want on to power the two mid and tweets plus sub.

on the lid? absolutely! depending on the dimensions of your amp it should fit without issue.

but mounting the amp on top would not result in a stealth install... it depends what you're after i guess.

my amps are currently screwed into an old wooden drawer which is inverted and bolted to where the spare tyre would be mounted. it's a temporary thing until i extend the wires for the Bose amp and find a suitable hidden home for both.

you can easily gain 30-40% more cargo space by removing the spare tyre and all the foam. but you run the risk of being stranded - mobility kits are futile for huge punctures so the other option is to fit runflat tyres. the lucky thing is the F10 BMW 5 series can be outfitted with identical sized tyres to our Z (assuming stock Rays 19") so runflats in our size do exist. Only problem is you're limited in choice and the tyres are designed for heavier cars, thus may not offer as much grip as the better non runflats like PSS.

anyway, that's for another topic

Hey guys glad to hear you all like my setup. The box is an enclosed setup and it kind of was a PITA to make. I can try to get the dimensions but you will have to give me some time since I have a lot going on right now... getting married in a month, closing on a new house and trying not to go crazy! I have the base model so no bose system so I did not have to relocate the amp anywhere.

Just give me a week and I can get the box out snap some pictures and take some measurements. I know when I mounted the subs in the box it was a pretty tight fit, and they barely fit in the box.

Thanks guys. This looks like something I won't be able to do myself. But I really like the look.

I personally do not even want to change the head unit in my car and will end up getting a jbl ms-8 to improve sound quality.

I think some new components, a sub(s) a good clean amp, and a jbl ms-8 should sound pretty great and will look completely stock

could you take some pic of your sub box, i really like that box. i think i would like to have one. just so i can see what it look like in that space.

axmea?

Congrats on putting dual 8's in a tiny enclosure. That is a good squeeze. I'm thinking smaller that mfr recommended ft.^3 by a smidge? Only if JL made dual 3 ohm 6" subs and put three of them. That would be more than enough for me.

I would like a box of my own preferably the one for the 2 8s anyway we can work a price out and maybe you can send me one pm if interested

It doesn't calculate to that. A 16" sub if there was one available, would have more AREA square inches compared to 2x8"

But yes 2x8 in a 370z is very sweet and more then enough. should be very tight.

Cool!

What do you guys think an estimate would be to build a box like that??

I like that box! Nice and Stealth.. Personally I don't like anyone seeing whats in my car. When I lived in Arizona people were always breaking into cars. I don't think it should cost too much if you get it right the first time. Wouldn't have to worry much about carpeting the whole thing either....

I was thinking of building it slightly higher, maybe an inch, and go with Alpine type R's or JL.. I suppose 2 DVC 8" subs might be too much??? Any thoughts?
