Ideally, you should paint MDF or plywood to seal it from moisture... Aluminium doesn't have that problem.

Thank u for the well written, and v humourous tutorial LOL , im a absolute beginner *least when it comes to car audio*, and this has helped out a lot.

Infact this entire forum is pretty kick ass!. B)

I am about to attempt to do the sound deadening on my doors tomorrow. Ive bought a dynamat extreme bulk pack which should definately be enough, but the only thing is i went down to bunnings to try and find the wax + grease remover and couldnt find any.

Where can you buy it?!

Im going to check out autobarn or repco tomorrow as i would assume they might have it. I'll let ya know how it performs

[brady123]

I bought mine from K-Mart

[Stone]

Bunnings usually has it in the solvents section.
Repco has it.
Other hardware stores have it.

i went to bunnings and bought a large roll of flash tack it not actlly attache dto teh roll liek tape is it, u unroll it an dthen peel teh backing off, i found no heat needed, but i say get 2 rolls ($30 each) tey even have smaller , skinner ones) as u the time i done teh outer skin on the 2nd door i was running lo oh and wer eteh holes wer ei just went right over it with sound deadner and abitt of gaffer tae.

how ever it was liek impossible for me to get a good layer inside the door but it will do.
i will buy 2 more rolls and do all the boot. still havent tested speake yet as teh suppled cable is about 1m 2 short ond i couldn't get the power wire to the boot stupid fire wall grrr lol

dont cover the water drain holes. you NEED them. Else your door will become a rusty mess after a while.

What car is it ? there should be existing rubber grommets in the firewall where the engine, lights, etc wires go through. Follow the engine loom to see where it goes through. Also check inside the wheel wells.

its an ef falcon sedan
tthe grommit is an wedge sup to the upper left of my brake booster i was not abl eto get a 4mm draw wire in there.
i havea large netal palte wewr eteh steering goe sthru i will drill taht.

i did not do teh bottom o fteh doors for that reason i and going to use thin sheets of foam in there to insulate it as well as to make teh space smaller

What is most beneficial - sound deadening the inside of the doors, the outer skin, or the actual door skin itself?

In the tutorial where it says to deaden the inside of the door, you're not talking about the section where plastic "vapour shield" originally was right?

Thanks

Septone wax and grease remover
Septone Body Deadner (4L)
Jaycar bitchumen bases sound deadner

looks alright. you can put foam between the door trim and the metal too to absorb some rattles.

Thanks

I would also like to know the answer to this....Cos i am about to start my sound deadening exercise tomorow!

[Low Tech]

When it comes to deadening the boot, where should i actually put the deadening?
Just take out everything and slay down deadening on anything that even remotely looks like metal or?

[Tim-E]

Just like to say that before reading this tutorial i had not a friggin clue how to sound deaden my doors nor did I know what the purpose of it was.
But i just copied most of this procedure and it had a huge affect on the performance of my new Focal splits, so cheers
