My DIY stealth sub box

[Dozer360]

Just thought I'd make a little thread of my stealth box install, its still not finished so I'll update it as I go.

Enjoy

Messing about with my old equipment just to see if it would fit

Trial fit

 

[Dozer360]

Took the carpet out

It already had some soundproofing

But I gave it some more (flashing tape as dynamat is well overpriced)

Taped it up, yes that is a lawn mower for £65 lol, the paper is because I couldn't get the dam masking tape to stick to the plastic.

Then taped it up some more over the paper

Now for the tricky part
***** Please note I have never used fiber glass before so it will probably mess up*****

This is taken after I messed up the mixture so I left it to dry while I got a lift to halfords to get some more

Then had another go and left it to dry over night, the next morning It was still a bit thin so I started on another layer

Then did half the mixture just to cover the corners as it started to rain
It may look like a crime scene but I need more resin again

Looking good so far, I've built one of these before for my old punto gt. It does take time but is a good little project and you'll save quite a bit as the genuine stealth boxes cost a fortune.

Tell me about it most are over £200, and all the stealth boxes I have seen won't fit a 15"er.

I'm also a strong believer of learning from your mistakes so by the time I have finished this i'll be an expert

Yes u will be lol. I remember having to drive around while the fibre glass set the smell is terrible.

Thought I'd do it while I have this cold, nose is so blocked I can't smell anything

Looking good so far. Something I have always wanted to try but never been confident enough to do. Is it realy that hard?

this will be my next project really missing bass now lol

Its messy, smelly, gives you a bad back twisting to get the top bit done;
But providing you learn from my mistakes and get enough fiber glass, resin and hardener, and you get the hardener to resin ratio right it's just like paper mâché for grown ups. I still need to get more resin to finish it off.

That's why I'm doing it, I had this sub in a massive box in the back of my mk2 mondeo and still had enough room in the boot for the Olympic stadium and half of Birmingham.
But the Leon boot is just a little bit smaller than a ducks but hole.

Great idea but for a big speaker like that you need more volume.
Looking at your sub it will have no more than 10 litres.

I agree, for it to sound right you need to calculate the correct volume needed for your 15" sub.

you can get fibreglass kits off ebay cheap http://www.ebay.co.uk/itm/Fibreglas...ultDomain_3&hash=item5648af39f2#ht_2666wt_952

looks like theres more than enough there thats how i was was going to do it, i'll either use my 12" alpine type s or buy a 10" type r

 

[Dozer360]

I did think about that but I have no idea how to work that out, and it will be kind of ported as I'm not sealing it behind the seats so I can still adjust the amp that's hidden on the back of the wood.
If you have any ideas on how I can work out how much volume I need then please tell me, I should be able to just move the wood further away from the side to get the right volume before I fix it all in.

Looks like the autoacoustic box's they sell at £180 but they only do them for a 10 or 12" sub

Thanks, I'll have to find the recommend volume for my sub from somewhere.
