XFIRE AUDIO OEM Series Components are designed for high quality sound systems. To get the highest performance from
your XFIRE AUDIO OEM Components we recommend:
•
To use 2-channels of an XFIRE AUDIO XFR1200.4 or XFR2000.4 amplifier to power the BMW42S system.
•
Make sure the active High Pass filter of the amplifier channels driving the BMW42S system is adjusted to the
recommended frequency (see specifications above).
