is this stuff really worth it? i have about 1000 watts in my trunk and its hard to even hear with my seats up in the back would this make it considerably louder?
sound deadener doesn't make your system louder it makes your vibrations sound less. if you have 1000 watts in the trunk and with your seat up you can barely hear it you need to relook at your installation and the products your running. I've run less then that and have had no problem hearing.
