How Much Dynamat For Front Doors? (r33)

[some_cs_student]

Hi,

I managed to grab:

3 * 18" x 32" (457mm x 812mm)

For ~$85 delivered, its on *ok* price, I'm starting to think I should have bought the xtreme bulk kit for ~$250 and got all 9 sheets but I'm only doing the front doors and I'm a little short for cash.

Will 3 sheets be enough to sound deaden the entire door? Both inner and outer skin?

I assume I might run out if I try and do the door trim?

Or....?

Thanks,

Gareth

no- 3 sheets will do the outside only. I would use the foam for the inner skin. (name escapes me.)

if you want a small pack flick me a PM and I'll sell you one.

As Chris said that wont be enough. I think i used about 6 sheets to do both of my front doors.

Chris, is there a benefit to using the foam or is it just a bit cheaper?

[Chris Rogers]

I used both in the corolla. dynamat outside and foam inside. foam helps cancel reflections and cleans the sound up a bit.

Hey,

Used a full 3 sheets on the outer skin and just made it

FHRX offered a reasonable price on the dynamat so bought 3 sheets and some diffusers from them, installed the tweeters today, and wired up the speakers.

Just need to make spacers (and will make them big because there big speakers) and more dynamat and I'm ready to go

Took some pics too, tweeters were not installed as well as I wanted but will work...(I re-used the window sail mounts of the factory tweeters).

If anyone wants the old plastic speaker mounts or speakers/tweeters PM me

you had me confused with the inside/outside bit. i have dynaxorb behind each speaker on the stagea and some equivalent on the R33. i had visions of you using some type of foam product that i hadn't seen.

[-Stokesy-]

Yeah that's what i was visioning as well.

[Chris Rogers]

and I was cofused as well. dynaliner is what I really meant.

[wolverine]

lol, i feel like George Dubya Bush at the moment.

There is way to much confusion in this thread

Does the dynalyner make that big a difference if you've already put dynamat on the inner and outer skin?

[Chris Rogers]

to me it did.

this is the product I confused everyone with.

i looked it up the other day and it is exactly like i was imagining originally.

neat that it can be installed under the bonnet (although i am guessing turbo charged underbonnet temps might challenge it a bit).
