What to soundproof with leftovers.....
Ok. I've done some soundproofing on my double cab and have some 3 sheets of dynamat extreme left.
Looking for an opinion on what will give me the greatest benefit to sound proof:

1) Roof
2) Bonnet
3) front doors (unless I have to remove plastic lining stuff!)

All floors, foot wells and seat box and rear bulkhead done.

Thanks in advance.

Rob

if it was me i would do 1 sheet on the bonnet insert pieces, then 1 sheet per front door Thumbs Up
or buy another box and do everything Twisted Evil Twisted Evil

Edit: just saw its a td5, youll need two sheets to do the bonnet inserts, then split one sheet in half and do the bottom halves of the doors Thumbs Up CSK Automotive

Thanks. Maybe I should buy a bit more ... But trying to save the pennies for the next big mod...
I will go for the bonnet first: do I need to cut templates for best fit and is the dynamat hood liner worthwhile, weighing up the cost/benefit and that I should be saving money!!

Cheers

You don't have to buy a pack, there is sheets you can buy. It's on E-bay.
I have two brand new rolls of tape (black) which I have had from late last year.
£15 for both if you wanted them, rrp about 20 ish.
Can't see me doing it this year.

As the roof is the biggest flattest panel that is most likely to "drum" I would put all three up there

Surly the biggest improvement will come from doubling up on the transmission tunnel Idea

As dynamat is a vibration damper it won't really make any difference doubling up on the tunnel unless it's very rattley

Thanks for the replies.
I haven't been using tape with the dynamat, should I have been?
Also running 1.2 disco ratios which seems to have reduced transmission noise/whine.

You should use the Dynamat tape to seal each piece ( the seams) and to keep everything in place.
After all if you don't do the seams it's not sealing it all properly.

You could always cut what's left into lots of very small pieces of approx 10mm x 20mm and insert one into each ear, they'd last ages Rolling with laughter

I'd go for the roof.

As dynamat is a vibration damper, not a soundproofer per se, you only need to cover approx. 25% of a panel to massively reduce the resonation.

^^^ +1 dynamat isn't a sound absorb er or blocker, it deadens vibrating panels! My 109 thread
