Well, here it is! I think I finally got to the bottom of the asphalt/butyl debate and have improved the tests to more closely match the real world.

As always, if anyone has information to improve this thing, I'm all ears.

Stickied. This guy put some serious time/thought/effort and probably money into this site/project, it deserves some recognition. I've read through the site and it's really well done and very informative. Everybody go have a look!

Thanks folks. Always happy to see this helped someone. Let me know how things work out for you. I couldn't believe what it difference it made for me.

I have a question that is related to this topic.

In our cars, once a trunk is fully matted what happens to our 6x9's or 6.5's in the rear deck when the bass from a sub(s) is pumping? With the trunk being matted (basically sealed) the only way to get that pressure into the car is through the seat cushions and through the almost solid deck lid. It seems like tremendous pressure in the trunk would turn our midrage/midbass drivers into somthing similar to a passive radiator, but not really passive. The pressure in the trunk should be plenty to forcefully move the cones of our smaller speakers, right? This must be bad for, and extremely hard on the rear speakers.

Do most people just take them out, leave the holes and only use front speakers?

I say take them out, if nothing else, for better SQ. Otherwise, consider making enclosures for them.

Deadening the trunk isn't going to increase the air pressure very much, unless you have a very leaky trunk to start with

The bass will come through the seat backs, but a lot of people like to enhance that by removing the rear speakers.

That sure is a pain. I suppose the whole trunk closing system would have to be revised to allow for enclosures under the rear deck speakers. I like the sound much better (with rear fill) than without it. In my car it seems very different and noticeable.

Thanks for the experiements and write up. Hopefully that company is hookin' you up with lots of free damplifier mat!

Sadly no.

That would make it an advertisement and just add to the confusion.

"You will also be adding some weight to the car. In my case, just over one hundred pounds. I choose to look at this as the weight reserved for one super-model. Since it would always have gone unused anyway, it was available for this purpose."

lmao... awesome article, excellent in-depth research... very valuable asset to all of us here in the I.C.E. community...

+1 for sure

It's been quite awhile since I've spent some quality time on the site so I figured I'd finally read this article... Very very detailed and this guy put some serious effort into that. Very informative!
