Mids are connected to the rear channels of the amp. Mids are cut off at HPF 63hz @ 12db/oct.
Sub is LPF at 63hz @ 18db/oct. I wish i could have the cut off slope at 36db/oct for a cleaner sub bass. At 63hz @ 18db/oct I think the sub would be catching frequencies till 100hz, whcih is kind of boomy bass :-(
