    Cheap Dynamat or similar sound deadening??

    I was tracing a buzzing noise from the sub enclosure this afternoon. Thought I'd fried the sub or broken something in the enclosure on a speed bump or what not. I opened the boot to check, no noise. Closed the boot and the whole of the bootlid resonates. Everything is tight, seems like the sub has found the resonant frequency of an Astra boot.

    Now I need to sound deaden the boot lid, but I want to do it as cheap as I can. Has anyone found a cheap source of sound deadening material?

    brown bread is cheaper than dynamat origonal and better. Other then that its roofing felt but it can be hard to use and to get to stick.

    If your on a budget the Flashing Tape from B&Q is much cheaper.
    The best seems to be Dynamat extreme.

    When I did it on my nova(many moons ago). I bought a huge roll(well heavy) of roofing material. Had a sort of plastic/tar??? subsatnce to it. I think it was about £26, but you could have easily done 2 cars all over with it. It worked really well.

    To get it to stick you had to heat it slightly, I used a hot air gun, but if you are patient, a hair dryer would work as well.

    roofing material will weigh the car down a good bit more than the brown bread. Think brown bread or dynamat origonal would be the best bet
