I have bought a Stealth 500W 12" Sub, Four 6x9's, 1600w 4 channel amp, 250w 2 channel amp and a 1.2f Power cap. I want to put in a pro looking boot install without needing to see my Mondy to pay for it. I know the sub needs 71L of air but I want to use as much of the boot as I can and not sacrifice my spare as I know I will need it 10 minutes after I remove it. I need the angle of the seatsplus make the sub higher and slightly wider so I can make it thinner. Can someone please advise me.

All I am asking really is the height of the boot on a Mk1 saloon from floor to just under shelf. Also the angle that the seats are at, I might be able to get the measurements if I know that.

Come on peeps someone with a mk1 please go outside in the cold n measure there boot depth

:innocent: :santa: :innocent:

Thanks for that Jamie

sounds silly but cant you just measure your own boot??

 

[BillyBob]

I've braved the cold and after hunting out all the bits, the boot height is 19 inchs give or take an inch, with a seeback angle of 10 degree's off the vertical.

If your looking info on the design and building of your enclosure, I found the following site a world of good when it came getting your enclosure size correct.

Thanks for that Billybob. Tried the site and it confused the HELL out of me. All i know by looking at the booklet that came with the sub is that for a ported box i need 47L and for a sealed box i need 71L.

Taking into account the angle of the seat and that i want it thinner and taller so as not to sacrifice the boot or spare wheel. I have come up with measurements which I really need someone to look over. The guy on the site will not accept emails asking for that. Could you or anyone on here have a look and see if I am going ok with it.

:thumbup: Send them to me and I'll give them the once over and see if your on the right track. :kaffeetrinker_2:

Cheers mate.

Measurements i got for a 47L Ported box are 51.25cm Length, 30cm base depth, 5cm top depth and Height from base to top is 40cm. I hope this is right but I would like so assistance with the angle. The Depth and Height are what I would like. It is just the angle and length that might have gone Pete Tong

Doesn't sound like 47 litres. More like 35.

 

[kettsmateoli]

Any help gettting it to 47L would be most appreciated

 

[magic919]

Make it 50% longer.

 

[kettsmateoli]

With the Base depth at 30 and the angle of the seats at 10 degrees. Have i got the top depth of 5cm right. I might be losing some volume there

 

[magic919]

You must be saying that the seat back is 10 degrees off vertical. So you'll have a top depth of 23cm then. That'll give a bit over 50 litres but makes no allowance for the thickness of material. Close enough then.

 

[kettsmateoli]

If I am using 19mm MDF. Will that bring it down

 

[magic919]

If you make these the external measurements it will come down a bit but not enough to be concerned over - jut the thickness of the material.

 

[kettsmateoli]

So what will the final measurements be then mate

 

[magic919]

If you want to go for 47 litres then make these measurements the external ones and construct the unit to be 45cm wide, 40cm high, 30cm base and 23cm top.

 

[kettsmateoli]

Thanks mate, would that be a ported or sealed unit, if ported where would I be putting the hole and how big would it be.

Sorry to keep bugging you mate

 

[magic919]

Per your own posting this is the right size for a ported box.

If the bumf with the sub driver gave you enclosure sizing then it ought to have a recommended port size.

It is possible to calculate but would depend on the Thiele-Small parameters for your driver. Have a look at the manufacturer's recommendation.

I'd have min 3" diameter tube and the length will depend on the frequency you want to tune to. You could position the port at the top. I'd need to dig around and check that as my sub enclosure was a sealed box.
