Buy some aluminium tape and cover the access holes and then cover with SD.. nice and easy

This got way to confusing

What got confusing?

All we are saying is that sound deadening and covering access holes can be dead cheaply and effectively within the $200 budget with money to spare.

Covering holes will create a psyedo enclosure that makes the speaker work better providing better output from the speaker. Only problem is then the doors vibrate due speaker performing better. So you then need to sound deaden.

So by doing both procedures at the same time, you save on time and cost later.
Material can be varied with a straight covering of the access holes with the SD material (assuming its a sheet) and/or other materials like MDF. You just have to varnish the mdf or make it waterproof to ensure that the mdf doesn't soak in water and start to lose composition in your door..

I just suggest aluminium tape as a resilient material that can conform to many different sized access holes in doors (incl the dreaded pulsar..) and something that is resilient to water and something that you can stick your SD to..

Using materials such as aluminium panel would be good, but the majority of inner door panels isn't flat and you'd have to ensure that the panel is securely attached (maybe not welded though, what happens when you break a window??)

MDF is cheap and so is aluminium tape.. see.. easy

how much is sound deadening material anyway. I want bang for the buck sound deadner, none of this 300% more for 1 poofteenth of a % better quality. Im not talking labour, I will do it all myself, im just curious as to the cost of material. Seems like an expensive excersise to me when you cant move it when you change cars

$130 for Dynamat Extreme to cover 2 doors. (iirc) There is cheaper options but thats one of the more top line SD's.
Worth the money for the difference it makes IMO

I'm sorry but I too have become really confused. Why will the MDF get wet in the first place? I agree with shiny_car that you would be wasting your money if you spend $200 to seal the holes, a layer of sound deadening does just as well.

Have a look through that. The MDF is painted, and SEALED with tape on either side. Even the wettest door shouldn't be able to get through that.

Quick and rather painless.

At most it'll cost you $100, may as well get it done. Or if you aren't fussed about it, then sure, a layer of sound deadening is fine. realise however that moisture makes sound deadening detach too.

I wasnt after knocking the shop.

As stated above its an older car, water can and or will get in the doors.  I have seen painted mdf after about 30mins in water (ie bit of rain), paint dont work.  So as also stated above it would be done properly once, using aluminium (which wont rust) sikaflex to seal it/stick it, and also rivits.  $200 was also just a figure, including product.

okay - i see where the whole confusion thing came from now..

Um - your doors will not be submersed in water for long periods of time..
the amount of water that would go through your door wouldn't be that much in reality..

and use aluminium tape.. that is not going to decompose in a door like MDF if you are so worried.. maybe some varnish then.. and seal with silicon..

SILVR6 - Dynamat Extreme is the top of the line stuff.. you dont' get anything better than that in the car audio world.. shame it costs so much - check out B-Quiet Ultimate for a near comparison.. competes well with DX and is far cheaper..

Why yes it is the old school brown bread, but better..

Zoiks - i don't know what is available in Australia, but i'm sure if you do some searching around the forum, someone would have mentioned a cheaper alternative.. i've heard G-Spot? or sound off form that australian company is quite good.. don't know where to source it from though.. anyone got a link?

[stazed]

G-Spot is $150/roll (which is 1.3 sq. m. and just covers two doors)

If you want cheaper then hit up Jaycar...
