After sweating my nads off today I finally finished my boot build.
The box is fibreglass moulded inside the spare and is easily lift-outable in case of puntures, I'll probably fit some mesh over the sub for a bit of extra protection but I can't deal with B&Q at weekends!

System details:
Sony CDX680 CD tuner with 6 disc changer under drivers seat.
Kenwood kac8401 amp
Infinity components in front doors
Pioneer TS-W305C 12" sub
Pics:
Boot floor frame
First layer of glass
finished box in boot frame
amp under passenger seat
Boot floor with flush sub This is where I'll add some mesh.
You'd never know what was underneath!

What do you think? Had a fiddle with some settings earlier and it sounds superb!

Cheers
Dave

 

thats a top install mate, wouldnt mind doing the same to mine...but can be arsed THB..although now ive seen it done...

 

That is a top job. IS the heat gonna affect the amp?
Do you have a photo of the CD changer please?

 

BTW. How much did you spend?

 

Dude that is awesome! Have to ask some questions:

How did you glass over the spare? Did you line it (with foil???) and then lay the glass?
How many litres do you think the "box" is?
Is the boot floor now higher than what it was before?
What's it sound like? Does anything vibrate/rattle?


I'm so impressed. Well done!

 

Cheers for the comments guys
In answer to your questions,
Hopefully the heat shouldn't affect the amp too much, it has an in built cooling fan and I rarely have the heating on anyway, just have to see how it goes.
Will take a pic of the changer tomorrow.
Lined the spare with masking tape and plastic sheet, then lined that with foil. Some of the foil stuck to the bottom of the fibrglass but you'll never see so I wasn't really bothered.

Then I cut some glass to form some corners which I stapled in place before I added the resin, that made it a lot easier to form the first layer of the box.
Box is approx 25 litres, but when I filled it with water there were still a few holes so it was a guesstimate.
Boot floor is now about 2" higher but you dont really notice it.
Sounds really good no vibration so far but I did line the boot with soundproofing before I started.

Materials costs:
Amp was about £120
Sub was £80
Amp wiring kit £25
MDF £8
Fibreglass was about £30 but if you find a bulk supplier it'll probably be cheaper.
All the other bits, speaker cable, brackets, filler, wood battens were all lying around the garage anyway so were technically free.

Thanks again for your kind words, hope this is helpful to anyone else who wants to give it a bash.

Cheers
Dave

 

Here's the changer under the driver's seat as requested.

fancy doing mine? Good job look forward to seeing the photo tomorrow

 

It's easy mate, just undo the four bolts holding the seat in, pop it out and it makes running the wiring a doddle.

Changer just screws into the metal of the seat with self tapping screws.

Doesn't take long at all.

Good luck

Dave

 

Oh my god......doing the same thing to my saloon at the moment cept without the spare wheel ! top marks on a quality install.

 

Also mounting both amps in the boot under the fake floor with perspex windows above and perspex window with holes for the sub....

 

DJ,

Excellent neat install! I really, really like that, as it's a superb example of (what I hope is) a good sounding install without losing any boot whatsoever.

Just one thing: you might want to disconnect/block off the air vents that go under the passenger seat, otherwise if you warm your tootsies you'll be warming the amp, too.

Very simple, and very nice job. I really like it.
Cheers,
Nick.
PS - can you tell I like it?

 

Superb job and an excellent idea.

 

Cheers chaps!
Your kind comments are much appreciated!
REALLY transforms the sound quality when on the move, and the other half even approves as the volume doesn't need to be cranked up to get the full benefit of the fronts.
I'm a very happy bunny!

Dave

 

Good job DJ. Given me some ideas for my next project.......

 

Very tidy piece of work, which leads me to post a potentially stupid question:

Would that kind of sub install work in a saloon?

 

Superb !!

It's Sub-a-licious !!

Now, wheres that old fiber glass shet I had .........

G TOMO

 

Sub-a-licious?
Forget the the fiber glass, go get your hat
Taxi for one!

Good job m8, I'd be very chuffed if I were you.
I've been planning a stealth ish boot build my self. Two 10-inch subs though + minimal loss of boot space...
This may of actually given my the inspiration needed to get off my ***!
Cheers

 

achad, two tens will fit quite nicely in the bit behind the seats before the main boot -
my old install didn't each much boot at all...

 

Hi chairk,

My thoughts exactly
A good friend of mine is a fiberglass so he's going to help me create something thats a little organic and blends into the boot. I've found some lovely material to then cover the fiberglass in, or alternatively if its a good enough job then I'd love to paint it the same colour as the car...

The Brief is to too keep weight to a minimum, keep sound quality as high as poss, maximize boot-space and make something that looks like it belongs there.

You couldn't get better then DJfish's solution, it's perfect but I've got my eyes on two 10's

The only thing I haven't sussed is how to secure them to the boot. I'm not too keen on making a mdf fake boot. mdf weighs a **** load!

DJ, did you cover the inside of the fiberglass with anything to prevent any 'tinny' sound? Or have you found that there isn't a need?

 

achad ......

I'm not shure that my hat would make a very good sub box ! ......

G TOMO

 

Sprayed the inside with Dynamat spray.

 

achad, mine was under the "hole" in the boot of a saloon if that makes sense. The rear, front and base (and internal partitions) of the box were 12mm mdf. There were three sheets of fibreglass on all of it, plus the bits that were MDF only were about 6 layers.

It secured to the boot by screws through the metal behind the seats going straight into the box, and by virtue of being truly a tight fit. It would never be able to move forward into the cabin due to the bulkhead being in the way, and the screws stopped it from moving backward. It completely filled the hole, so lateral movement wasn't on the cards.

Any more questions, drop me a line.
Nick.

 

damn nick! wish you had left that bit in ...

(i bought Chiark's classic a while back)

 

Naah, it'd still be too heavy for your performance dreams now

 

(probably spot on there )

 

DJ Fish,
Cheers M8

Chiark,
Thanks for the that.
I'll let you know when I start it and how i get on.

Anthony

 

Sorry for resurrecting this thread and turning it into a shameless plug but I'm selling the car and as I'll probably end up trading it in I'm stripping all the sellable bits off first.
If anyone's interested in buying this stuff its for sale here

Cheers
Dave
