There is one born everyday....
Subs in the doors is just wrong.
Even the OEM "door subs" were just
mid bass drivers.
Bass is omnidirectional and subs belong in the trunk
in a sealed/ported enclosure, not in the doors in a
free-air configuration.

It all how you cross them over that makes them subs or mid bass drivers.
Fair nuf?

An active 24dB/Octave high pass filter would be needed before the
amplifier in the low level domain like the shakers do....
