Yaris Sedan Deadening and Sound system upgrade

[derickveliz2]

BTW, about 2 month ago or so I made a big discovery, and I challenge everybody to try it out, specially if you have a trunk with a subwoofer in a box.

While playing your favorite song seating in the drivers seat, have somebody open the trunk!

Does the Bass goes up or down?

I did (fig.2) this and the Bass increased considerable, it's called "cancellation" (fig.1) I had the subwoofer facing forward behind the rear seat, then I rotated it facing towards the back. (fig.3)

I test it again, and this time the Bass didn't increased but my Bass had a bigger punch! no "Cancellation" anymore.

I had my subwoofer and amplifier working harder to accomplish the Bass, now without "Cancellation" (fig.3) I have a better Bass and my amp/sub is running more efficiently.
