No, I think hes serious. My friend has 2 T1 12's run off of a ZX1500.1 in his Camaro and those fuckers are loud, but when he closes the windows you can barley hear anything. He has 120 ft^2 of eDead in the back and the only thing that rattles is the door handles.

You said deadening materials, but does it really matter that much? The reason I ask is because I've seen 2 Legacy 12"s (I know, stop laughing, I promise they weren't mine), on a backseat in a small sealed box facing forward, that you could hear coming real far. Inside the car, it wasn't the greatest by any means, and I KNOW your equipment is MUCH MUCH BETTER, that's why I don't understand. I'm thinking you're using the term "Barely hear the Burb", very loosely. Enlighten me with any ideas if you can plz.

Pssshhhhh.. Barely heard it?? It set car alarms off like 50 foot away

A out of tune box will produce loud bass out of the vehicle. It takes a few feet for a sound wave to form. Depending on the frequency it is grater or lesser. So when you tune your box you take that into consideration the size of the box port size and placement all affect the sound wave. A improperly tuned box will cause the sound wave to finish forming out side of the vehicle there for causing it to be louder when driving by.

I was told that when you use deadening material you actually gain dbs. So how do you gain db if you become quieter on the inside?

Unless you're doing MECA driveby, there is no reason to want to be loud on the outside.
