Front/Rear high pass, using a 2 channel amplifier for mono sub bass
The combination of a 2 and a 4 channel amplifier, utilizing their built in crossovers, makes it a snap to put together a full system with front and rear highs, with mono sub bass.
Interconnect cable checklist:
-Using good quality RCA cables, feed the front and rear outputs of a head unit to the inputs of the 4 channel amplifier as shown.
-Also connect the LINE OUT of the 4 channel amplifier to the LINE INPUT of the 2 channel amplifier as shown.
Mono bass woofer wiring:
Connect the mono speaker positive terminal to the CH4 +, and its negative terminal to CH3
