If you have problems with the mid bass driver
"reaching the bottom" (the voice coil touches the
bottom pole plate) at high volumes, use the HP-
filter to avoid this with a setting at 50 - 80 Hz or
higher. Make your own tests.
A7 IN BRIDGE MODE
You can connect the stereo channels in
bridge mode if you prefer. Connect
between L+ and R- on the respective
channel pair.Use Y-cables to feed the same
signal to FRONT left& right channel pair,
