soundproofing v70

[expolicev70t5]

Having been in a couple of x5's & a Q7 I was inpressed with how quiet they are inside. I was therefore thinking about adding some sound proofing to under boot floor, and under rear seats to make car a bit quieter. I've been looking at 6 mm thick closed cell self adhesive sound proofing that is on ebay. Has anyone else done this and does it make much difference? If you have what products have you used.
Thanks in advance Paul

Would dynamat be better for this

Do you know if if made much difference sound wise? Looking at what Lee did is exactly what I had in mind, matting I had been looking at was Dodo sound proofing, but if Dynamat makes a big difference then I might go down that route

Sorry for late reply.
Yes, it did make a difference. The bass from the sub has more depth and its quieter in the back in terms of road noise.
I've not got round to doing the front doors yet, but they will get done in the spring.
There is definitely less vibration.

Thanks Lee for that, will definitely go down that route then and from what you've said I think I might do doors as well
