I recently bought three rolls of dynomat extreme...is this going to be a waste of my time for my trunk, or should I go ahead and do it? My trunk rattles, pretty bad, I have 2 12" JL Audio's powered by a 700 watt amp, so it hits fairly hard...

If I do go ahead and use the dynomat are there any things I should do to my trunk before I put it down. And do I take out everything so my trunk is down to the metal? Thanks for your help in advance!

 

I used it...made wonders of difference. The bass is much cleaner and most inportantly...NO RATTLES!!!! you may need more than 3 rolls to do your whole trunk though. It's best to take everything out of the trunk...system, carpet, spare......and the metal should be clean too. Not dirt and stuff. It's not a waste of money or time IMO.
