Hi I have 1800 watt (900 rms) watt amp running on my sub. My trunk in my maxima rattles way too much . Do you guys think I should add a single layer or a double layer of dynamat to my trunk? And how much dynamat do you think I will need for a single layer to cover my trunk? I found a 20ft trunk kit I'm not sure if it's enough thanks

Wrong section. Why don't you measure it out?

Go With dynomat extreme.. or a better product like Second Skin and you won't have to do a double layer. If applied correctly, you shouldn't have to do a double layer with anything. Are you talking about youre actual trunk rattling or your license plate? What sub and amp are you running exactly..

oh.. and WRONG SECTION

Sorry guys I didn't realize I posted this on the wrong thread but I have a 1800 watt kenwoodAmp with a 3000 watt 12 inch alpine type x. My whole trunk rattles. The bottom part of the bumper the insde backboard that goes below the window where speakers usually go on other cars and my trunk lid rattles

To mention it was a 1800 watt mono d class amp

You may want to ask this question in this section. and don't forget to put some thin jute or maybe even some wool behind your licence plate.

go with second skin damplifier pro and for an extra sound barrier you can do luxury liner pro.

check for the writeup on innerbean to see where all the rattles are on the back deck.

^^^ LOL. Off topic, but that just made my day.
