I did the floor with black tar stuff from supercheap, I would imagine you could do the roof with that too.

Tar stuff works ok on the roof. But with what your going to be running i doubt it will make a difference. The sound deadening mat sorta stuff u can get is a hell of a lot more effective but pricey.... but even then it's designed more to deaden sound... than prevent vibration.

Im not sure what you are trying to acheive... the roof is going to flex no matter what u do.

Best thing i found to do was to remove the roof lining and check the condition of where the roof beams are glued to the tin... in alot of cases they come unstuck and make excessive vibration... using sickaflex in between the beams and the roof tin is perfect to fix this.

When i had my extream system in my subi wagon the roof was the least of my worries... stopping the change in my coin holder from rattling at the keys on my key ring was my main problems.

finally got around to doing it
made a huge difference

also gluing the roof bars back on made a big difference too

is that BOTH boxes?

looks good- should be VERY quiet now. do the rest of the car if you have any left.

i was going to do one sub either side of the back... but because of the rattling and everything i just left it at one

its at the stage where its pushing the windows in and out of the top door seals and the exterior touring wagon mouldings are vibrating now ... more work to do

i reckon i will get around to doing the whole carbut only had enough for the front doors tailgate and roof

will be getting another bulk pack off you when funds allow 8O

I've decided to do this to my brumby when I get home so does any one have a rough calculation of the cab surface area excluding the glass of course, for the doors I will be doing a double layer.
