The plate amp is a mono unit.After hooking up to the plate-amp,you will need to run the PlateAmp positive to the 1st sub positive+,then run a wire from the Negative on SUB to the POS on the 2nd sub.2nd sub Neg to the PlateAmp Neg.These plate amps are meant to drive 4 ohms and above.Check the impedance:stated is generally 8 ohms with actual impedance at 5-6 ohms.If they are truly 8 ohm,then you could run parallel to the two sub enclosures:jumper the Pos together and the same thing with the Neg on subs.
